Glowing under blacklight

I’ve heard that in the 1960’s, blacklight posters were all the rage.  Glowing things are cool!  How does blacklight actually cause things to glow?  

“Blacklight” is an invisible form of light that operates in the ultraviolet range.  Because light takes on a wave form, the frequency of the peaks and troughs in the wave are known as wavelengths.  In the visible spectrum, reds and oranges have the longest wavelengths, and at the other end of the spectrum, blues and violets have the shortest wavelengths, meaning they have higher frequency.   Ultraviolet light is not visible to us, yet exists beyond the violet shade.  The wavelengths of ultraviolet light are grouped into 3 bands: A, B and C.   

UV-A, with wavelengths ranging from 320-400 nanometers (nm), is the safest form of UV light and often referred to as Longwave UV.  This kind of UV light is generated by Blacklight units (the dark purple fluorescent tubes) as well as UV LED flashlights.  Black lights are considered safe for use in the home as well as theatres and night clubs etc.  Most quality sunglasses will protect eyes against UV-A.  

UV-B, at 280-320nm wavelength, is the one that can cause sunburn when over-exposed. It can also be used in the medical treatment of certain skin conditions.  Most quality sunglasses will protect eyes against UV-B.

UV-C, at 200-280nm wavelength, is totally absorbed by the Earth's atmosphere, but also widely used as a germicidal sterilizer in hospitals. 

Obviously, UV light has had good and bad press.  As you may know, certain types of UV light are known to cause eye and skin damage and cancer.   And certain types of UV light are used to kill microbes, making the air you breathe (or surfaces you touch) safer.  We have a whole article on some of the ways researchers are using UV light to sanitize.  In this article, however, we’re going to look at some of the more useful ways to use blacklight (UV-A) in your life–to literally “see” the invisible!

Blacklight makes some of the invisible, visible, because it illuminates items that fluoresce.  These items contain exposed phosphorus atoms that reflect short wavelength UV light back to our eyes. For instance, paper shines under a blacklight because of the fluorescent chemicals added as a whitener. (Using Blacklights to Find Pet Urine)

Urine glows under UV light because it contains phosphorus. 

Pet Urine:  Unlike the synthetic fluorescents added to white paper, natural fluorescent substances such as dog and cat urine etc, do not glow brightly under UV. In fact, they are generally quite dim, so do not expect a supernova!  You will be looking for patches a little brighter than their background; you’ll know them when you see them.  Cat urine glows particularly well under a black light, as it contains high levels of phosphorus, but the intensity of the glow can vary depending on the animal’s diet and health.  When examining soft surfaces like carpet and fabrics, remember that liquids can quickly soak down into them, so that not a lot of urine remains on the surface to “glow”. It’s also easier to find it:

• When fully dried, because liquid or damp urine will not glow.
• When new–the “glow” slowly fades over time as the urine ages.

If you do find “accidents”, try a cleanser that uses enzymes.   You can read all about enzyme cleansers in our article.  (Stain Detective Pro)

Rodent Urine: Rats and mice are incontinent and will urinate and defecate on the move, up to 80 times a day! This means you will be looking for a trail of urine droplets or streaks leading in the direction of travel. Urine and droppings are deposited where the rodents spend most of their time and where they travel.  Amino acids in rodent urine will fluoresce, or emit light of a different color, when exposed to ultraviolet light. This makes it possible to see rodent, rat, mouse, hamster, guinea-pig or squirrel urine even in dark places. (Rodent Detector Pro)

Mold often glows under blacklight.  In this video, mold stains that are not visible in normal light are shown on the ceiling under blacklight.  If you are not seeing stains in an area that has leaked before, or has a high level of humidity, the key may be to shine the light at an angle against the wall.  You should shine the ultraviolet light closely along the sides of the suspected surface or walls. The angle of illumination will show the presence of fungus, however, some cleaning products also leave a glow, so be careful not to mistake cleaning residues for mold. (How To Detect Mold With A Blacklight)

Hand Washing: Blacklights make it possible to see if you are washing your hands effectively and make training on hand-washing easy!  If you apply some UV Germ Grease (which simulates the way germs cover your hands; it’s just a clingy grease with glowing particles), wash according to this video and check them under blacklight to see if any of the grease remains, you’re more likely to get your hands cleaner after this training.

Here are some other interesting items you can get to “glow” in your home: (Got a new UV torch? Here are some things to shine it on) 

• Tonic water – the quinine in tonic water glows blue
• Honey – the aromatic molecules in honey can glow green
• Turmeric root – the curcumin in turmeric glows yellow
• Eggs – a compound in eggshells called protoporphyrin IX can glow red
• Rocks, jewels and gemstones – lots of minerals glow under UV light
• Cash – banknotes have added photoluminescent details to prevent fraud
• Cleaning materials – detergents (including laundry detergents) often have photoluminescent molecules to make them easy to see
• Highlighters and dyes – fluorescence is a type of photoluminescence, so fluorescent markers and dyes will often glow under UV light
• Vitamins: Vitamin A and the B vitamins thiamine, niacin, and riboflavin are strongly fluorescent. Try crushing a vitamin B-12 tablet and dissolving it in vinegar. The solution will glow bright yellow under a black light. (16 Things That Glow Under Black Light)
• Antiques that have been repaired or touched up will glow or fluoresce differently in the area where the repair has been made.
• Insects such as scorpions glow bright green, and Harvestman (Opiliones, also sometimes called Daddy Long Legs) glow blue, as do certain other spiders.

Here are some tips about selecting UV blacklights: 

• Although many people associate blacklight with a purple light, if you can see the light, it’s not blacklight, and the contribution of visible light diminishes the ability to “see” any hidden markings. 
• The frequency of UV light emitted determines the quality of results obtained.  There is a sweet-spot for UV which is between 365nm and 385nm.  However, to manufacture LEDs capable of emitting in this frequency range is far more expensive.
• There are different types of lamps that are used to make UV light:
  • Mercury vapor lamps are used in theaters and large spaces where it’s needed to project UV light over a distance
  • UV fluorescent tubes or bulbs are smaller and more portable, with decent quality
  • UV LED lights: these come in a wide spectrum of quality (wavelengths), but they are very portable and consume little energy.

So....I went sleuthing one night with a small, inexpensive blacklight borrowed from a friend, and it works!  First I looked around some registers I knew had sweated when I had an older, less efficient HVAC system, and there they were--old stains and mold that was not even visible in the daylight (I have some popcorn ceilings so shining the light at an angle really accentuates the stain).  Next, I looked and saw a white patch where stains had been "touched up"--proof that not everything was stained or mold.  Then, I found a pet stain in a small rug that had absorbed and was unnoticeable in daylight. 

A small blacklight flashlight could be a cool science project for you and your kids, by not only finding things that glow, but eliminating the yucky animal pee and poo as well with enzyme cleansers.  Remember that the wavelength (365-385nm) is important to get quality black light, and many cheap flashlights don’t fall in that range. Here are some lights that will give the best results for your detective work:

• uvBeast New V3 365nm MINI - Black Light UV Flashlight, $40: at 365nm wavelength, you should see no visible purple light but anything that glows should light up well.  It’s rechargeable!
• LUMENSHOOTER S5 UV Flashlight, $70:  This flashlight illuminates longer-distance so you can go sleuthing outdoors or in the shed. It’s also rechargeable.
• Glowtech blacklights, approx $31-43 excluding shipping.  This UK company really knows their blacklights, they ship worldwide, and are also the creators of the hand hygiene training products.    

What are xenobiotics and POPs and how do our bodies deal with them?

Xenobiotics surround us everyday!  If you have an illness that you can pinpoint to a chemical or environmental exposure, then you know what a xenobiotic is and how it can seriously affect your health.     

• Xenobiotics have been defined as chemicals to which an organism is exposed that are extrinsic to the normal metabolism of that organism. (Progress in Molecular Biology and Translational Science).  Since mold produces mycotoxins that are not made in our own bodies, these mycotoxins are xenobiotics to us, as are many man-made chemicals like POPs. (Alcohol is also a xenobiotic).

• Persistent Organic Pollutants (POPs) are chemicals of global concern due to their potential for long-range transport, persistence in the environment, ability to bio-magnify and bio-accumulate in ecosystems, as well as their significant negative effects on human health and the environment. The most commonly encountered POPs are organochlorine pesticides, such as DDT, industrial chemicals, polychlorinated biphenyls (PCB) as well as unintentional by-products of many industrial processes, especially polychlorinated dibenzo-p-dioxins (PCDD) and dibenzofurans (PCDF), commonly known as dioxins. (Food safety: Persistent organic pollutants (POPs))  POPs are fat-soluable, and tend to accumulate in our fat tissues. POPs are xenobiotics, but not all xenobiotics are POPs. Exposure to POPs has been associated with diabetes, cardiovascular diseases and many other chronic diseases. (Glutathione!)  

Most of these xenobiotics are transformed by enzymes in the liver, and are then eliminated by excretion.  First of all: What is an enzyme?   Enzymes are complex proteins produced by living organisms that act as catalysts in chemical reactions.  Enzymes can either build up or break down.  Enzymes themselves are not consumed.

This is where our genes come in.  “GST” genes are important for detoxification of the body, in that they manufacture those enzymes that facilitate the detoxification reaction.  One of the most important GST enzymes is GSTP1.  

The GST pi gene encodes (provides instructions for building) the enzyme Glutathione S‑transferase Pi (GSTP1), which plays an important regulatory role in detoxification, anti‑oxidative damage, and the occurrence of various diseases.  The detoxification reaction is called “glutathione conjugation”.  (GSTP1 and cancer: Expression, methylation, polymorphisms and signaling (Review))  Following is an example of glutathione conjugation; note that the “SH” site on glutathione (sulfur) is the binding site for the xenobiotic:

Source: The role of glutathione-S-transferase in anti-cancer drug resistance

GSTP1 has a wide range of physiological functions: It is involved in metabolism, detoxification and elimination of potentially genotoxic foreign complexes, metabolizes a variety of carcinogenic compounds, and protects cells against DNA damage and canceration.  However, while GST mediates detoxification from accidental xenobiotics, like exposures to pesticide for example, GSTs have also been implicated in the development of resistance toward chemotherapy agents, especially platinum-based chemotherapy drugs. (GSTP1 and cancer: Expression, methylation, polymorphisms and signaling (Review))

Here are several more genetic terms that will help to understand how GST and GSTP1 work: 

• Gene expression is how GST directs the manufacture of GSTP1 (for more on how gene expression works, check out this article)

• Methylation is a chemical modification of DNA and other molecules that may be retained as cells divide to make more cells. When found in DNA, methylation can alter gene expression. In this process, chemical tags called methyl groups attach to a particular location within DNA where they turn a gene on or off, thereby regulating the production of proteins that the gene encodes. (National Human Genome Research Institute)

• Polymorphism, as related to genomics, refers to the presence of two or more variant forms of a specific DNA sequence that can occur among different individuals or populations. The most common type of polymorphism involves variation at a single nucleotide (also called a single-nucleotide polymorphism, or SNP). Other polymorphisms can be much larger, involving longer stretches of DNA. (National Human Genome Research Institute)

GSTP1 methylation can affect gene expression, inactivating the GST gene.  GSTP1 methylation has been associated with the development or recurrence of prostate cancer (PCa), liver and breast cancers. 

In addition, during detoxification of xenobiotics, GSTP1 may become damaged, causing polymorphism (a variation).  Some polymorphisms are associated with specific cancer types. For example, the genetic polymorphism of GSTP1 may be associated with the detoxification of polycyclic aromatic hydrocarbons (PAHs) in cigarette smoke and exhibits the highest expression in lung tissue.  More polymorphisms of GSTP1 and associated cancer risks are shown in the next table:

Source: (GSTP1 and cancer: Expression, methylation, polymorphisms and signaling (Review)) 

Therefore, xenobiotics can not only overload the GST detoxification processes, but they can damage GST and the enzymes it encodes, like GSTP1.  Restricting xenobiotics and stress is crucial to keeping this important defense system working optimally!

Here’s a bit more on how these genes detoxify.  Although GST genes do not make glutathione (GSS genes do), they regulate its use.

Glutathione has been described as “the mother of all antioxidants” because it recycles vitamins C and E, which are other antioxidants, and of course it binds and modifies toxins from our environment so that we can get rid of them.  According to Dr. Mark Hyman, “The secret of its (glutathione’s) power is the sulfur (SH) chemical groups it contains. Sulfur is a sticky, smelly molecule. It acts like fly paper and all the bad things in the body stick onto it, including free radicals and toxins like mercury and other heavy metals.” (Glutathione: The Mother of All Antioxidants)

Glutathione (GSH) is a tripeptide molecule consisting of the amino acids glutamate, cysteine, and glycine. It is the most abundant antioxidant in the human body that contains thiol (an organic sulfur compound).  Peptides are chains of 2 to 50 amino acids that are linked together.  For reference, proteins are also chains of amino acids linked together, but these number over 50 and usually more than 100. Here is a visual aid, noting that Glutathione falls under the Peptides category. 

Source: The Difference between Peptides and Proteins

Glutathione exists in two states in cells: reduced (GSH) and oxidized (GSSG).  Oxidized glutathione is actually 2 reduced glutathiones bound together at the sulfur atoms.

Source: Glutathione!

The difference between reduced and oxidized glutathione is that GSH (reduced) is the “recharged” version, while GSSG (oxidized, also called glutathione disulfide) is the “spent” version. GSH is also called “free glutathione” in that it has its sulfur site ready to bind to xenobiotics, while the site on the spent version is not available because it’s stuck to another glutathione molecule. 

The body is constantly recycling glutathione from the oxidized to the reduced version (for more on how this happens, this video is really helpful) .  Healthy cells at rest have a GSH/GSSG ratio >100:1, meaning that there is much more GSH (recharged) available than GSSG (spent).  When cells are exposed to oxidant stress such as xenobiotics, the ratio can drop to 1:10. This is very dangerous, because depletion of GSH and accumulation of GSSG is actually directly toxic to cells, causing their death (apoptosis).  (Glutathione!)  

Glutathione (GSH) production also drops with age and disease. Unfortunately you can’t just “pop a pill” for more GSH (contrary to many medical claims on the internet!). The body, however, can  make its own GSH in the liver with the amino acids cysteine, glutamate, and glycine. The best ways to boost our bodies’ manufacturing of GSH are to eat foods rich in glutathione or its building blocks (amino acids of cysteine, glutamate, and glycine), increasing your intake of vitamin C, and getting enough sleep and exercise.  (10 Natural Ways to Increase Your Glutathione Level)

Here’s a recap about GST, GSTP1, and glutathione:

• GST is the gene responsible for encoding GSTP1.

• GSTP1 is the enzyme that regulates the ability of glutathione to bind to xenobiotics.

• Glutathione is an an enzyme that exists in 2 forms: GSH (reduced) and GSSG (oxidized).

• GSH is also called “free glutathione” and in healthy cells, exists in a 100:1 ratio with GSSG.

• Xenobiotics are those chemicals to which we are exposed that come from outside our bodies.  POPs (persistent organic pollutants) are xenobiotics.

• GSH binds with xenobiotics in the presence of the GSTP1 enzyme.

• GSSG cannot be used to bind xenobiotics, it first must be converted back to GSH.

• Stress and xenobiotics are dangerous in that they can cause changes to GST and GSTP1 which affect their ability to detoxify our bodies, making the body prone to cancer.

• Unchecked stress and xenobiotics also overwhelm free glutathione, causing cell death.

• We can help restore proper glutathione balance and immune function by limiting stress and xenobiotics, eating the right foods for manufacture of GSH and getting enough sleep and exercise.

Cancer may be a case of nature AND nuture: Why it’s time to pay attention to Inflammogens

The New Yorker article “All the Carcinogens We Cannot See” is quite eye-opening.  You’ve probably known people who lived a “bad” life, drinking or smoking or doing drugs, to a ripe old age, and then also a number of “innocent” young victims of cancer.  What’s the rhyme or reason of evading cancer or acquiring it?   This is the question that thousands of scientists engage every day as they test chemicals on bacteria or animals.  In the 1970’s, biochemist Bruce Ames was able to measure that many mutagens are carcinogens: if a chemical or toxin causes a mutation in bacteria, then it’s likely to also be a carcinogen.  Thus, the Ames test for mutagens remains the standard lab technique for screening substances that may cause cancer.  However, there are many chemicals that cause cancer but are not obviously mutagenic, such as diethylstilbestrol (DES), which increases the risk of vaginal, cervical, and breast cancer.  Also, it has been discovered that with or without exposure to mutagens, most people have a small number of mutated genes.  What is the “trigger” that begins cancer growth?

A well-known example is cigarette smoke.  It contains more than 60 mutagens, which are by extension carcinogens. Surprisingly, however, in a 2023 study that examined the characteristic fingerprints of DNA damage caused by cigarette smoke in human lung cancers, ninety-two per cent had the mutations associated with the DNA-damaging substances in smoke. But about eight per cent lacked this kind of mutagenic damage, and clear mechanisms of cancer in between 8-10 percent of smokers is lacking, causing scientists to think that there are missing cancer-causing agents.

Other studies have confirmed that a second agent is necessary to “activate” the mutations into cancerous tumors.  In one study, DMBA, a cancer-linked chemical that was found in coal tar, only caused cancer in a small percentage of the mice that were exposed to it.  However, after adding an inflammatory oil after exposure to DMBA, more than half of the mice developed malignant tumors.  In another study, mice with a powerful cancer-causing gene only developed cancer when they were also plagued with poorly healing wounds, causing chronic inflammation.  It was inflammation that triggered tumors. 

What does this tell us (other than animals do a lot of our dirty work)?  It’s not mutagens alone that cause cancer:  in many cases, malignancies are only activated when another environmental toxin causes chronic irritation that catapults them out of normalcy. “The mutant cells just lie there,” according to Allan Balmain, a cancer geneticist at the University of California, San Francisco.. “It’s the inflammation that awakens them.”

Unfortunately, there are a lot of sources of inflammation.  According to the Cleveland Clinic, the some of the most common reasons for chronic inflammation in the body are autoimmune diseases, exposure to toxins, and untreated acute inflammation, as from an infection or injury.  Then there are lifestyle factors such as drinking alcohol in excess, obesity, chronic stress and smoking. 

Air pollution also featured prominently in The New Yorker article, and it’s a frequent topic in the news today in expected areas (cities and industrial zones) and unexpected areas (wildfires in the wilderness).  In fact, British epidemiologists Richard Doll and Austin Bradford Hill, who are celebrated for determining the primary cause of lung cancer–smoking–also correlated the disease to proximity to major roadways, gasworks, industrial plants, and coal fires, and thus, by extension, exposure to high levels of air pollution.  Since then, it’s been discovered that when lung cancer occurs in people who have never smoked, the malignant cells often carry a mutation in a gene known as EGFR.  Using data from the U.K., South Korea, and Taiwan, researchers found that in each of the three countries, tthe higher the level of air pollution, the higher the incidence of EGFR-mutated lung cancer. This confirms a link between air pollution and nonsmoking-related lung cancer by mutation.  But there is something else in the air pollution besides mutagens, and it is inflammogens.  Again using all mice that were genetically primed to have EGFR mutations, mice who received larger doses of a liquid simulating air pollution (PM2.5) in their lungs, had more tumors.  The PM2.5-treated mice were full of inflammatory cells.  It seems to be the combination of mutation AND inflammation that caused the mutation to develop into cancer.  Looking more closely at the inflammation, macrophages (large cells that eat foreign particles) promoted an immune response by secreting interleukin-1 beta, a potent inflammatory signal,. If the interleukin-1 beta was blocked with an antibody, the effect of air-pollution exposure dissipated.  Accordingly,  immune-deficient mice did not have inflammation and defeated the effects of air pollution.

Whew, that’s a lot of science.  What we can take away is that inflammation could be the invisible criminal accomplice in many cancer cases, as well as in other diseases.  There’s been a big focus on knowing your genetics, and firms like The DNA Company recognize that purposefully changing your lifestyle with better food, exercise, less stress and sometimes specific supplements can mitigate the effects of DNA deficiencies by defeating the accomplice, inflammation.  In this spirit, we hope that whether you get your DNA tested or not, you are aware of the air quality in and outside your home, and do your best to avoid inflammation by ascribing to a healthy lifestyle and less stress.  These include cleaning often with non-toxic cleaners like TotalClean, changing your HVAC filters regularly, using masks and HEPA filters where necessary, and using bi-polar devices  like the Germ Defender, Upgraded Air Angel Mobile or Whole Home Polar Ionizer that can also help purify the air of VOCs and particulates.  (For more information about your immune system at a molecular level and specific ways to build it up, check out our article here).  The answer to disease, like the cause, is two-fold: take the physical steps you can avoid toxins and inflammation, and sort out the mental toxins (stresses) that cause inflammation too.   At HypoAir, we wish you a healthy home and year!

Tenant Rights to a Habitable Home: Mold and Smoke Issues

What can a renter do when their home becomes “inhabitable” due to mold or second-hand smoke?

When tenants sign lease agreements with building owners or landlords, they agree to abide by certain rules while living at the property, which protect both the tenant and the landlord.  In the US, certain tenant rights are protected under federal, state, and local laws.  For the purposes of this article, we are going to examine a tenant’s right to a habitable home.  

The “implied warranty of habitability” is the legal term for a renter’s right to a home that keeps out rain and snow, has sufficient hot water and heat, sturdy walls and floors, free from environmental dangers such as lead, asbestos and mold, and reasonable protection from criminal intrusion.  According to Nolo.com, all states except one (Arkansas) recognize the implied warranty of habitability.  Even if a landlord offers lower rent in exchange for the tenant “waiving” habitability rights, such waivers are typically not upheld in court.  There are differences between habitability problems and “minor repair” problems, though, so that landlords are not legally required to fix every problem that elicits a complaint. 

For purposes of safety and air quality, some habitability problems may be:

-a roof leak or plugged air conditioner drain that results in moldy walls

-improperly vented water heater that causes exhaust gasses to leak into the apartment/home

-neighbors that do things that cause you to be unhealthy, like smoke inside, make a lot of noise during sleeping hours, etc.

If the landlord does not acknowledge or repair the problem, there are ways that tenants can enforce the implied warranty of habitability.  If this applies to you, make sure that you have properly notified the landlord and given them time to respond, and then you may want to notify the local building inspector.  Be prepared, however, to move out if the inspector deems the problem causes your home to be uninhabitable!   “Bigger stick” actions for the renter include, depending on state laws:

• withholding rent
 (make sure you are completely up-to-date on rent before withholding it for habitability reasons)

• paying for repairs yourself and deducting the cost from the rent
 (also make sure you are completely up-to-date on rent before doing this)

• sue the landlord, or 


• move out without notice (break the lease) and without liability for future rent. 

To check whether your state has a precedent for withholding rent or paying for repairs and deducting them from your rent, you can check this page.  Here is more information about these options. 

Specific problems that constitute inhabitable spaces:

Although mold can be a serious health issue, there are no federal laws regarding permissible exposure limits or building tolerance standards for mold in residential buildings, and only a few states and cities have established guidelines regarding mold in indoor air.  (Nolo.com)  Because of the following, it has been difficult for tenants to get landlords to fix or compensate for mold:

• Mold causes a plethora of symptoms and health problems that are not exclusive to mold

• Blood or urine tests are the only way to confirm its presence in the body

• There is are many types of molds present in most homes and rentals, however, only a few have been implicated in serious health issues (such as Stachybotrus Chartrum or Aspergillus)

• The term “toxic mold” is not a legal term, but the above mentioned species are “toxigenic”, meaning that they can produce mycotoxins.  

There have been successful lawsuits; in 2021 a Florida jury awarded $48 million in a habitability/mold case. (TysonMendes.com)  This is an exceptional compensation, but the vast majority of tenants living with mold that causes health problems do not get any compensation, sometimes due to weak local and state laws on habitability.  For example, in Washington state there are no explicit protections from mold for tenants, and the law doesn’t hold landlords liable when they don’t provide the “mold addendum”. (whyy.org) Here are what legal experts recommend to make your voice heard (based on advice from a Virginia lawyer in this video):

• Make sure you notify the landlord or owner of the problem in writing and the way prescribed in your lease, and document all communication with them about the problem.  Describe the condition of the area, photograph it, include any lab results and any health effects that may have come from it.

• If the landlord does not respond or fix the problem, in Virginia you can file an official document called a Tenant Assertion and Complaint.  Definitely check with legal experts on your rights to withhold rent or move out (which as stated above, vary from state to state; withholding rent is not allowed in Virginia).  

• If you believe health issues have resulted from the mold, it’s best to contact a specialist or personal injury attorney.  

Second-hand smoke and vapors are a serious problem in multi-family dwellings.  This document from the American Lung Association and Public Health Law Center at Mitchell Hamline School of Law outlines tenant rights to healthy air inside their homes, and guidelines on options available to them in California, including:

1. Approaching the neighbor who smokes/vapes.  They may be unaware of the impact it’s having on you or your family.

2. Contacting the landlord, if the smoking/vaping doesn’t stop.  Always document your communication with the neighbor or landlord.  

3. Reviewing your lease and ask the landlord in writing to enforce the non-smoking clause.

4. Reviewing local laws, as they may have specific requirements to force landlord action. 

5. California allows withholding of rent, however this could trigger an eviction response from the landlord.  In this case, uninhabitable conditions is a reasonable defense, and if the landlord does evict, the courts will decide whether rent abatement is appropriate. 

6. Lawsuits include small-claims court, which is used for claims $10,000 or less, and trial court, which in general is only used when there has been substantial harm from repeated, significant exposure to secondhand smoke.  Appropriate charges against the landlord would include breach of contract, disability claims, nuisance claims, covenant of quiet enjoyment, and constructive eviction (if the tenant is forced to move out because of uninhabitable conditions).  

Are Tiny Homes built from Sheds a Good Idea?

At least every other day, I see an ad for a tiny home or office that companies or individuals built from what used to be backyard “sheds”.  Now, don’t get me wrong, I am all for repurposing buildings and materials, when they are done the right way!  (In fact, I even repurposed a large metal workshop building into a 2 bed/1.5 bath “condo” for my parents.  This one is on a concrete slab and for all intents and purposes, could have been built that way as a home). What are the advantages, and what are the cautions, of making a home from a shed?  (Many great points adapted from Living in a Shed: 9 Things (2023) You Must Know):

The advantages to living in a tiny home are many, for example:

• Up-front cost is cheaper than a house
• Smaller utility bill
• Less square footage to clean
• Less impact on the environment
• Privacy
• Portability
• Customization
• Ability to live in nature or “off-grid” more easily

However, “sheds” are only a subset of tiny homes, specifically, tiny homes that started out as prefab backyard buildings.  Let’s take a look at what could go wrong from making one of these into a habitation.

First of all, when considering whether to build out a shed as a home, you should check into local building codes.  If you live within city limits, there are likely laws about what type of buildings can be built or placed on your property to become “habitations”.  Plopping a shed down and running electricity to it for your teenager to live in could be a big problem whenever it’s noticed by the building inspectors!  Moving it to the middle of a few acres in the country doesn’t normally pose these legal issues, but again, it’s best to check with your local building inspector!   If it’s illegal to live in a shed, it may be legal to live in an ADU-an Accessory Dwelling Unit.  For example, ADU’s in California are required to be at least the size of an efficiency unit (at least 150 sq. ft. livable space plus a bathroom), they must contain a kitchen, a bathroom, they must be built on a permanent foundation, and must be able to turn on/off the ADU utilities without entering the primary unit.  (ADU vs Finished Shed Comparison)

Construction: This is the largest area of caution we see.  Within this topic, we need to highlight: 

• Off-gassing of toxic compounds from interior building materials.  If the building was never meant for habitation (even as a chicken coop!), then it may contain building materials that are rated for “outdoor use only” which may give off dangerous pesticides/weatherization chemicals.
• Inferior flooring and framing techniques:  We’ve seen them: sheds built to hold push lawnmowers and Christmas decorations may not hold up to daily living over a number of years.  Holes or loose joints that develop inevitably allow pests to come in (they want to be cool/warm/fed too!).  
• Inferior foundation: Setting a shed on a few cinder blocks is typically not sufficient for daily living and if the floor begins to sag, all kinds of structural issues (including leaks and mold) can ensue. 
• Poor insulation:  Typically, storage sheds only need to keep the paint from freezing, not keep a person comfortable, so insulation may not be optimal.  This includes roof and floor insulation–yes, if your shed is not mounted to a slab foundation, it needs to be insulated!
• Improper sealing (which can cause moisture infiltration and mold growth): If siding is applied over the frame without an air or vapor barrier, it’s easy for moisture to condense inside the walls if they are heated for a living space, or similarly cooled during a hot summer.  These steps in normal construction are what inspectors look for, for the safety of the homeowner and longevity of the building.
• Addition of water and sewage facilities warrants several considerations:
  • Where is your water source and how will you deal with sewage?  Sewage service is probably the biggest hurdle to overcome, as there are 3 options which may or may not be permitted in your locale: connection to the city’s sewer system, installing a septic tank, or installing a composting toilet. 
  • Plumbing in sinks, toilets, showers and drains also is done by code for a reason–leaks can cause serious mold and hygiene issues.  It’s not a good idea to buy that shed if these appliances are added without proper spacing and materials by someone who knows plumbing code.
• Addition of power to the shed:  Sometimes power service to a shed (50-100 amp service) is not what you would get for a normal home (200 amp service).  Like the plumbing, wiring the shed for power should be done by someone who knows electrical code, so that it’s wired safely!
• Addition of HVAC to the shed: Sticking a “window unit” AC or space heater in the side of the shed may keep you cool or warm if it’s the right size, but without proper ventilation, you could build up CO2 and mold very quickly.  CO2 is the product of insufficient ventilation, and face it, a shed is just a small, closed room unless proper ventilation is planned and built-in!  The mold can result from simply living in that closed room, because along with CO2, every human exudes water vapor through their lungs and skin.  If there are 2 people living there, the air quality will be even worse.

So far, it may sound like a major “NO” to use sheds as homes, but that’s just not true.  If you’re allowed to use one in your locale, you can safely do so by starting from scratch (buying a bare-bones model) or buying one from a builder that knows good home construction.  Then you can make sure that the construction, outfitting and customization will work for years to come without causing health issues.  Let’s face it, home ownership is expensive, but saving on a tiny home just to live uncomfortably from lack of weatherization or get sick from mold is definitely not worth the savings.  Therefore, planning is essential!

How to Balance Wildfire Smoke and Work

Wildfire smoke from Canada in 2023 has made the northern and eastern states in the US look like a Martian landscape at times.   If your job requires you to commute to the office, whether it’s one day a week or everyday, what should you consider before taking off for work?

First things first:  how is your employer reacting to this problem?  Employers and employees have been pivoting ever since COVID-19: office, home, office, schedules, communication, and air quality.  It’s a juggling act, and this new challenge (ok, maybe new for these areas, not so much for west coasters) is another fire drill.  Hopefully, everyone can continue to work together to get through it, safely.  Does your employer recognize that air quality from smoke is a safety concern just as much as viruses?   According to Thomas Brugato, counsel in the Washington office of Covington & Burling who focuses on environmental matters, as well as civil and administrative litigation, companies need to be asking whether the systems they have in place are “adequate to ensure protection and safe air during very bad air quality events”.  (How wildfire smoke should change the way companies think about return to office)  Generally speaking, companies have a duty to provide a safe work environment under federal Occupational Safety and Health Administration (OSHA) rules. 

How this applies to your commute

Technically, under the “coming and going rule,” employees are typically deemed not engaged in work while commuting, so generally, employers are not liable for wrongs committed during that time.  (Are you responsible for an employees’ commute?)  However, if you are in a job that has already redefined “office” because of air quality, to commute or not commute is now also an air quality decision, and hopefully an informed one!  If your employer is not familiar with the air quality reports at AirNow.gov, you’ll need to find a tactful way to introduce them in order to know what everyone will be facing on their commute. 

Even if you’re in a vehicle with the “recirculation” mode on, the outside atmosphere WILL come inside.  We’ve addressed vehicle air quality in this article, and changing your cabin air filter on a regular basis, especially with one that includes activated carbon, can drastically improve air quality in your car.  (Cabin air filters should be changed every 15,000 to 30,000 miles.)  Wearing a mask inside your car can also help with mild smoke conditions; it will not filter noxious gasses, but will help with particulates.  If you’re using a company car, try to find out when the cabin air filter was changed, and push for doing so if it’s overdue.  You can also ask for your employer to reimburse mask expenses for commuting. 

Research your route!  It may take a bit longer to drive through cleaner air, but it’s certainly worth it for your health.  Free apps like AirNow, BreezeOMeter and google maps (they have a new air quality “layer”) can show where the air quality is acceptable. 

Do you normally walk or bike to work?  In a 2017 review of 39 studies, scientists discovered a few conundrums that are worth considering: 

• although biking and walking exposes you to less pollutants, the uptake of pollution is higher because you are breathing more frequently and deeply by reason of exercise

• the years of life expectancy (YLE) gained by walking or biking compared with motorized transport are positive, meaning that cyclists and pedestrians actually gained years in life expectancy despite inhaling more particulates, due to the positive health effects of physical activity.  Cyclists gained more YLE than pedestrians because the average commute for pedestrians took longer.  

However, this study did not take wildfire smoke into account.  Because particulates from smoke are an additional burden, walking or biking on these days is not recommended!  Any other mode of transportation (car, train, bus, subway, etc.) would be advised over walking or biking on low air-quality days due to wildfire smoke.  If you don’t have a car or are close to public transportation, ask your employer or coworkers for help commuting during low air-quality days.

How this applies to your workplace

Although office workspaces usually have a HVAC system with a filter, sometimes they can be overwhelmed by bad air quality outside, especially if people are constantly entering and leaving, or service windows are being opened and closed.  It’s helpful to bring a portable air quality monitor with you and keep it at your workspace, to determine if air inside the building is healthy.  If particulates are high and changing the HVAC filter does not help, here are some ways to improve it:

• recommend trying a higher MERV filter (MERV 13 should help)

• recommend getting a standalone HEPA filter, if possible with activated carbon

• recommend increasing cleaning during this time, as particulates settle into dust which can be disturbed and inhaled

• If office-wide improvements are not welcomed, add a small air cleaner with HEPA and activated carbon to your space. 

• Lastly, using a mask during the workday or part of the day is not pleasant but it is better than breathing polluted air!

If you work and are locked into being at a specific workplace, discussing air quality with your employer and coworkers can bring this problem to the forefront, and may also generate some creative solutions!

Optimizing Your Window Air Conditioner for Maximum Clean, Cool Air

Global average temperatures have exceeded recorded highs several times in the last month, and articles on ways to keep cool are proliferating!  In this article, I don’t have any “new” way to keep cool, but if you are among those blessed with a simple window air conditioner, let us help you make it work just as well and as efficiently as the day you bought it!

Window air conditioners are the humble yet hard-working appliances that many households can’t do without.  As one of the oldest cities in the US, New York City has an abundance of window units because about 75 percent of the buildings throughout the five boroughs were constructed before 1960, according to the NYC Department of Buildings.  (Why about a quarter of US households are stuck with ugly and loud window AC units)  The cost of retrofitting these old buildings with central air conditioning is way too high, so window air-conditioning units are the solution, and continue to be for many households across the US.  However, even if your window air conditioner is an older unit, a little time and effort can go a long way in helping it cool better, work less (lower your energy bill), and put out better quality air! 

If you have the option of upgrading your window air conditioner, there are many worthy options out there, including those with inverter motors, which save a lot of energy and control humidity better.  (To understand better what inverter technology is, check out our article here.)  Unfortunately, no one has combined an inverter air conditioner and premium filtration, but you can get premium filtration on a new air conditioner with the Friedrich Kuhl units.  These units cool (and some also heat) rooms by heat pump, with smart controls (wifi enabled and smart home compatible) AND they have MERV 13 filters available (a MERV 13 bracket kit is needed).  Until manufacturers put inverter units and premium filtration together, we have to put premium filtration in priority!

If your existing window air conditioner has a few more years of life, it helps (although not necessary) to know how a window air conditioner works.  In the first part of our article “What kind of air conditioner do you have?” we explain the workings of this type of unit.  A key lesson is knowing that unless you have a ventilation lever on your unit, there is no mixing of indoor and outdoor air.  (Check out this video to find out how to find and operate a ventilation lever.)  Therefore, the air conditioner is not pulling in outside air, it’s only recirculating indoor air.  Whatever dust, pet dander and microbes are floating around your apartment can get lodged in the air conditioner and grow into disgusting science experiments that will negatively affect your air quality!

Therefore, a clean evaporator coil is super-important.  The evaporator coils are what change your hot and humid indoor air into cooler and drier air.  Because most window air conditioners come with a flimsy clean-able filter that would qualify somewhere between MERV 1 through 4, what really ends up filtering the air is the coil–because after a season of running constantly, so much dust and dirt go through the cheap filter and get lodged in the coil!  This is not only disgusting, it’s unhealthy.  Therefore, if you’ve operated your window unit for more than one summer and never cleaned the coil, please start with this step to eliminate the majority of grime that’s lodged there.  (Be sure to have help removing the air conditioner from the window, especially if you live on an upper story!) 

After you’ve cleaned your unit (and the included filter), check that it is blowing cold air well.  It should blow air that is 15-20 degrees colder than the air it takes in.  To measure this, simply use a portable temperature gauge above the unit (out of the stream of cold air) as the intake temperature, and then move the thermometer directly into the cold air coming out, and note the difference (it’s also helpful to note the difference in humidity, to know that it’s actually removing moisture as well!).  Our portable humidity sensors will give both temperature and humidity.  If the difference in inlet and outlet temperatures does not approach 15 degrees F for a clean AC unit, then you can check into getting the refrigerant topped up.  This is best done by a licensed HVAC technician.

Next, it’s not too hard to upgrade your current filtration so that the air coming out of your air conditioner is cleaner than the air that goes in!  Here are some options:

• Frigidaire now offers MERV 14 filters for some of its models.  Check the link in the overview for compatibility.
• You can cut a regular HVAC filter to fit as per this video (make sure you use painter’s tape around the edges to prevent air leaking around the filter), or 
• You can have a custom filter bracket made for your window AC, and change the filter in it often. Since the louvers in front just thwart air flow, you can actually remove the louvered panel and fit the filter inside (if it has a rectangular filter), or you can fit the filter over the louvers and secure it to the front with double-sided tape.  In order to specify the correct size for your window unit, determine which louvers are the “intake” (moving air into the unit), and measure the area covering and slightly outside of them, so that the frame and tape will seal but not cover a lot of the louvered space. 
• You can make your own frame from 1” aluminum “u-channel” and rivets, and purchase the filter material in bulk or cut to size (these media pads are equivalent to MERV 8 and will filter a lot more dust than the cleanable factory filter!)

Finally, placing a Germ Defender or Mobile Air Angel near the air conditioner will not only help to freshen the room as ions are carried with the fresh air, it will also help to keep the coils cleaner as ions are sucked into the air conditioner by killing microbes and mold spores inside it.

If your space is feeling stuffy from being closed up all the time due to hot weather, chances are CO2 levels are rising.  Fresh air ventilation is important, so go ahead and use that ventilation lever on your window air conditioner, or crack the windows in the morning or evening when temperatures are more tolerable.  If you live in an urban or dusty area, use our window ventilation filters to get fresh air without the particulates.  May our window air conditioning units live long, cool lives!

Wash your hands AND your wristband!

Their popularity never seems to diminish, and where there’s one, there’s usually a stack of them: wristbands.  Silicone is a popular material choice because it is flexible, durable, can be colorful, shaped into wide or small bands, and even hold useful appliances like smart watches and gym passes.  However, depending on the material and the wearer, wristbands can carry harmful germs that don’t get as much attention as they should. 

According to a study by Florida Atlantic University's Charles E. Schmidt College of Science, there is a correlation between the material (plastic, rubber, cloth, leather and metal (gold and silver)) and the prevalence of bacteria.  Plastic and rubber had the highest incidence of bacteria because they tend to hold moisture between it and the wearer’s skin, and foster microbial growth unless some sort of antibacterial coating is incorporated.  Not surprisingly, gold and silver had virtually no bacteria (these are age-old non-toxic anti-microbial materials due to the ions they release).  

The other variable was the activity (hygiene) of the subject at sampling time. (no significant differences between males and females were detected in the occurrence or distribution of the bacteria groups).   This means that more activity (exercise) and specifically going to the gym, increased bacteria counts.  Here are the types of bacteria monitored:

• Staphylococcus and Pseudomonas, which are common skin residents.  The highest staphylococcal counts were found on wristbands from gym-goers.  Besides the skin, Staphylococcus aureus is a type of bacteria found in the nose, armpit, groin and other areas, and causes a wide variety of diseases. Pseudomonas spp. can cause infections in blood, lungs (pneumonia) or other parts of the body following surgery. 

• Intestinal organisms of the genera Escherichia, specifically E. coli: these are prevalent in the bathroom and can land anywhere on you after you flush a toilet (don’t fear, we show you how to protect against this here).  However, raw foods in the kitchen are another source for these bacteria.

Thankfully, the study also investigated what types of cleaners were the most effective at reducing bacteria: 

• Lysol™ Disinfectant Spray and 70 percent ethanol were highly effective regardless of the wristband material with 99.99 percent kill rate within 30 seconds.  While Lysol has been trusted for disinfection for many years, it’s not non-toxic: most of the spray can formulations earned an “F” rating on the Environmental Working Group’s website.  Instead, try hypochlorous acid, like this Force of Nature Starter Kit.  For more about hypochlorous acid, check out our post here. 

• Apple cider vinegar, a common “DIY” cleaning ingredient, was not as potent and required a full two-minute exposure to reduce bacterial counts.

Although they weren’t tested in the study, we do have some simple alternatives to help you wear your wristbands with less germs:

• If it’s flexible enough, turn your wristband inside-out once in a while during the day to expose the underside to light and air.  The UV rays in sunlight, as well as the ions in fresh air, kill germs!

• Although many wristbands can be worn 24/7, it’s a good idea to take them off after showering to let your skin and the underside of the band dry out.  Leaving them off overnight is even better.

• Hand sanitizers:  Sanitizers are super convenient when soap and water is not available, so whenever using it on your hands, spread some around the wristband and your wrists. The same goes for washing your hands–just make sure to rinse off the soap.

If you decide to upgrade your rubber silicone wristband, think gold or silver.   In this case, you will get what you pay for–less germs!

Get more fresh air ventilation with Nanofiber Window Screens (Easy DIY Project!)

If you’ve never thought about them, it’s time to give your window screens some attention.  If your windows open, you’ll want to have screens that are clean and in good repair to keep out insects and other creepy crawly things (won’t go into what could possibly come through an open window).  It’s even more important in seasons of extreme heat or power outages to have a way to get fresh air.  Keeping your windows closed all day can cause levels of CO2 to build up in your home that cause drowsiness and inability to focus or concentrate (check out our article here), so it’s best to let some fresh air in whenever the outside air temperature, humidity and quality permit.

Window screens have been around for a long time (like the 1800’s!) but even age-old products can get an upgrade, making our lives easier.  This upgrade doesn’t have to involve AI or “smart” anything, requiring the internet and electricity.  In this case, window screens have been upgraded with a new material, nanofiber.

Traditionally, window screening came in several varieties of material and color, such as aluminum and fiberglass, and black, silver, gray or bronze colors.  Standard screens have a mesh size of 18 by 16, meaning there are 18 squares per inch from the top left corner to the top right corner (also referred to as warp) and 16 squares per inch from the top left corner to the bottom left corner (also referred to as fill). (Replacement Window Screen Buying Guide)  These are able to prevent most flying insects from passing through, but they do allow a lot of dust and smaller particles to pass through.   The use of nanofibers (each fiber is less than the width of a human hair) allows the holes to become much smaller, because they are spaced very closely, allowing air but not fine particulates to pass through.  Voila!  Nanofiber window screens offer protection from the next “pest”, dust and allergens.  By just replacing the screens you already have with nanofiber material, you can save yourself some cleaning, coughing and add the ability to open your windows more often because of this protection.   What’s even better is that it doesn’t take a lot of time or special tools (just one cheap one) to replace the screen material with some new nanofiber screening.

Here’s the DIY part: replacing your screens with nanofiber screens is a homeowner project that just takes a few hours and supplies.  If you’re not familiar with how window screens are held in place, they are held into the narrow channel on the screen frame with a rubbery spline, or cord.  

There’s also an ALTERNATIVE INSTALLATION with Magnetic Tape (which is practical if your screen frames are broken or missing).  Scroll down to the bottom of this article for the alternative installation.

Here’s what you’ll need for the traditional installation:

• The nanofiber window screen (order yours here)

• Spline (if the spline in your screens is not cracking or falling apart, you can reuse it)

• Window screen rolling tool, $4

• Small flat-head screwdriver

• Sharp utility knife to trim the screen after installation

There are lots of videos online showing how to replace screens, but I like this one for its simplicity (step 1 starts at 1:50).  Here are the basic steps:

1. Remove old spline and screen

2. Size and align new screen over the frame (1-2 inches extra on each side)

3. Push screen into channel on first side (using the convex side of the tool)

4. Insert spline into grooved screen and channel (using the concave side of tool) (Repeat steps 3 and 4 for other sides)

5. Push spline into corners using screwdriver, trim excess screen carefully with utility knife

And here are some additional tips:

• If you have to get new spline, take a small piece of the old stuff to the hardware store in order to select the right diameter.

• Some people like to hold the frame in place by taping it to the work surface, but this doesn’t allow you to rotate it easily if you can’t access all 4 sides of your work surface.

• You can use a gallon of water or full can of paint to help hold the screen in place to get started.

• Some people like to use the spline in one length, bending it at the corners as you go around; some like to cut it at each corner. 

• Be careful not to press too hard on the spline as you work, in case your tool slips, so that you don’t cut the screen accidentally.

• Normally you shouldn’t have to “stretch” the screen, just gently smooth it out, while rolling the last two sides, as you don’t want too much tension on the frame when you’re done.

• If you get too frustrated or find that one of the screen frames is broken, many small hardware stores offer “rescreening” services and repair of the frames; just bring them your nanoscreen with the frame(s).

It may take a little more time to get your first screen replaced, but you’ll get better as you go along and have some new functional “filters” in your windows.  Sit down to enjoy the fresh, clean air and admire the fruits of your hard work!  After a few months, you will notice dust collecting on the outside of your screens as they do their job, but you can easily clean them by removing them and using a gentle spray of water on them from the inside out to wash off the dust.  If necessary, use a mild detergent like liquid dish soap or car wash soap and a soft brush to remove any stubborn dirt or bird poop. 

Nanofiber window screens can help you breathe easier all year long, because let’s face it, there always seems to be an “allergen” in the air.  They can also cut down on the dust going onto your HVAC filter, your TV screens, your rugs and furniture—you name it!  Maybe most importantly, they can help you open windows for fresh air more often and be prepared for a power outage in the summer, when open windows (but not dust!) are a necessity.  

ALTERNATIVE INSTALLATION:  Many times the screen frame is broken or missing altogether, or you’re just not sure about doing the traditional install yourself.  Instead, you can use Magnetic Tape to install the screen.  The kit has everything you need to make a nice, flexibly-framed screen that installs easily over your window frame.  (Note that you’ll need to remove the screen to open or close the window, but that’s easy to do.)  The video on the product page gives step by step instructions.

Navigating Electromagnetic Frequency (EMF) Radiation

Convenience and technology go hand in hand.  If you want to save money at your store, the store’s “app” gives you the deals straight to your cellphone.  Smart doorbells and smart thermostats keep us safe and comfortable.  Baby monitors and cameras help us to keep an eye on the kids.  What could be better than knowing and doing more than your parents ever could?

The only problem with these perks is the energy they emit while helping you.  It’s called electromagnetic frequency radiation, or EMF for short.  Now, don’t get me wrong.  Anything that uses electricity, even a washing machine motor from the 1960’s, will have an electricmagnetic field associated with it, because that’s what electricity does.  Electrons move inside the electric supply cord, back and forth at the rate of about 60 cycles per second (60 hertz) in the US.  When the motor is energized, the electrons moving through the coils of the motor generate an electric field that spins the drum, and another motor that pumps out the water.  Electricity is right up there with indoor plumbing as something we wouldn’t want to be without!  

There is a big difference, however, between the way an old washing machine and a new cellphone use electricity and emit radiation.  The old washing machine had two modes, on and off, and it used power straight from the wall (110-120 volts alternating current, 60 hertz) with no transformers, inverters or rectifiers involved.   The cellphone, however, could never be plugged into the wall because it uses low voltage (12 volts) and “direct current” (DC).  The charger is plugged into the wall to convert high AC to low DC voltage to feed it to the sensitive electronics of the phone.  The phone, once charged, is essentially a battery with several different modes and the ability to radiate signals in a radius around it (about 30 feet for Bluetooth).  This generates two different problems with it: the way the charger manipulates electricity (taking the AC and converting it to DC and lowering the voltage) and the way both the charger and cellphone emit radiation.

“Dirty electricity” is admittedly not easy to understand.  After all, electricity is promoted to be the world’s cleanest energy, right?  We are enticed to replace everything that emits carbon with newer appliances that are “greener” for the planet with “no” emissions.   Yet, there is no such thing as free.  There are trade-offs for every convenience and savings in the pocket don’t always mean a savings to our peace of mind or health.

Since dirty electricity can’t be seen, smelled or touched, the best way to describe it is in pictures.   The photo below is of an alternating current electrical signal.  (If you don’t understand the difference between alternating and direct current, here is a really good video). The bright green line is clean power, which in alternating current is a smooth rolling sine wave (the peaks and valleys occur 60 times per minute, hence 60 hertz).  The green fuzz is dirty electricity, which is made up of jagged spikes that cause more radiation and can cause damage to equipment.  Where does the green fuzz come from?

Source: What is Dirty Electricity?

The green fuzz, or dirty power, is what is left over when you convert AC into DC or maneuver it in other ways.  Here is a video that visualizes what the little transformer/rectifiers on your cellphone charger and laptop chargers are doing to convert the power from the wall (120 volts AC) into usable power for your device (12 volts DC).  Chopping up the signal and smoothing it out causes some power “noise” and energy wastage.  Have you ever felt the transformer plug of the phone, or of your laptop computer?  Heat is another sign that there is energy being wasted.  

The green fuzz is not just ruining a nice picture of a sine wave.  The spikes and unpredictable energy can cause damage to electronics as well as to our bodies.  Dirty electricity can cause the following health issues (What is Dirty Electricity?) :

• Headaches
• Sleep Disturbances
• Fatigue
• Tinnitus
• Cognitive Impairment
• Heart Arrhythmia
• Mood Swings
• Weakening of the nervous, endocrine and immune systems
• Increased risk of serious chronic illnesses such as cancer

Why does dirty electricity affect us?  Because we, as humans, run on electricity too.  The nervous system that regulates many functions in our bodies is electrical, and its sensitive equipment and signals can be affected by outside electromagnetic radiation.  For example, scientists have known for a while that some types of EMF radiation can actually cause bone to grow, and calcium channel blockers (which are frequently prescribed for heart arrhythmias) block EMF effects because they block electrical activity in the body. (Electromagnetic fields act via activation of voltage-gated calcium channels to produce beneficial or adverse effects)

Many health effects are only manifested when a major change occurs, like the installation of a smart meter on our home, or a newly installed cellphone tower coming online nearby, or moving into an apartment with wi-fi signals surrounding yours.  However, symptoms can also be gradual as well.  Like the effects of mold and mycotoxins, EMF radiation seems to affect those who are most sensitive to them.  When most of the population are not affected outwardly, regulation of new and more profuse radiation is not a priority.  However, quantified effects on our microbiology such as blood, organs and DNA through research should be enough to increase awareness of its dangers.

Although governments and health organizations (including the WHO) have denied that there is any risk to our health from dirty electricity, here is a short list of studies that have shown there is a cause and effect.  Since animals are even more sensitive than humans (termed “canaries”), included are a couple of real-world case studies on how EMF has affected farm animals, with detrimental effects on their behavior, output and reproduction.

• Electromagnetic hypersensitivity: biological effects of dirty electricity with emphasis on diabetes and multiple sclerosis
• Power quality affects teacher wellbeing and student behavior in three Minnesota Schools
• Microwave frequency electromagnetic fields (EMFs) produce widespread neuropsychiatric effects including depression

• Wi-Fi is an important threat to human health
• Conspicuous behavioural abnormalities in a dairy cow herd near a TV and radio transmitting antenna
• Report to Michigan Oversight Committee regarding effects of stray voltage on dairy cattle 

The good news is that you can take control in your own home and eliminate some causes of dirty electricity.  Dimmer switches and compact fluorescent bulbs (CFLs) are some of the worst offenders, so try to eliminate these in your home.  Unplug computer and cellphone chargers whenever they are not in use, and when they are in use, keep them as far from you as possible.   Special paints, coverings and cases can help to shield you from harmful EMF--you can check out these types of shields here. 

Other sources of EMF radiation can be controlled as well: 

• Smart meters: Smart meters are power meters that broadcast a signal similar to your cellphone, to the electric company so that they can monitor power usage remotely.  Although many utility companies claim that their meters only “broadcast” less than a minute per day, the pulses sent by the meter (typically 3 milliseconds each) can be over 10,000 times per day.  (Frequently Asked Questions about Smart Meters)  If you can, opt out of having a smart meter placed on your building and have it replaced with an analog meter.  If you cannot, there are meter cages available that can significantly block EMF radiation from the meter.  This video shows how high and frequently EMF radiation can be emitted from Smart Meters.
• Wireless routers: Unplug wireless routers at night and place them away from bedrooms or areas where people spend extended periods of time.  
• Baby Monitors: Research the baby monitor you use to see whether it is safe, and place it a safe distance from the crib or bed.  
• Cellphones: Restrict cellphone use by children and for adults, opt to use headsets or  speakerphone as often as possible, carrying the phone in a purse or away from your body.  
• Solar power inverters:  the process of converting low-voltage direct current into high voltage alternating current produces dirty electricity, which can build up over time to dangerous levels inside your home.

There are two types of devices that can detect EMF radiation: a Graham-Stetzer meter that measures dirty electricity in GS units (I’ll discuss this next), OR simply an AM radio!  AM radios can pick up low-order harmonics.  Tune it down to the lowest amplitude, about 500 kHz, to start, and turn up the volume a bit to hear the static.  Bring it near a possible EMF emitter like a cellphone or its charger plug, and listen for an increase in static or “ticks” to indicate it is emitting EMF radiation.  You can also tune the amplitude up to its highest, to about 1600 kHz, to see what’s going on there.  (This setting is better for “hearing” the EMF from your cellphone, which typically broadcasts on even higher frequencies).  This video shows how to use an AM radio inside your home to detect relative volumes of EMF radiation from different appliances (the dimmer switch really puts out a lot)!  Another video shows you how to detect whether EMF radiation is coming from the line power (from the power company), or from the devices, like lighting and electronics, in your house.  

If you find you have a lot of EMF radiation with the AM radio, then you might want to invest in a more quantitative meter that shows the real levels of radiation.  With a meter designed to detect EMF radiation, you can walk around your home to measure these levels.  The original meter, called a Graham-Stetzer Microsurge meter (after its inventors) measures EMF radiation in units of “GS”.  According to Dave Stetzer, a GS unit is a measure of the energy on electrical wires generated by high frequency transients and harmonics, and is influenced by voltage, amplitude and frequency. (presentation by Dr. Magda Havas, PhD).  According to one electrician, under 200 GS is good and acceptable, but Dr. Havas has noted that those who are more sensitive and already have health issues like diabetics and multiple sclerosis patients, require readings under 40 GS.  In order to reduce EMF, a “Stetzerizer filter” can simply be plugged into any normal electrical outlet.  This video shows how to use a Graham-Stetzer meter and Stetzerizer filters to get rid of dirty electricity.  After removing as many offending appliances as possible like dimmer switches, CFL bulbs and unused electronic charges, the filters are very easy to use–just plug them in! 

If you have unexplained or chronic health issues, it’s worth exploring and measuring EMF radiation in your home.  This type of pollution can’t be seen, smelled or heard but the health effects on many people are debilitating, and intervention can provide significant relief.  We hope you will do your own research on EMF radiation!
