What Our Clients Say About Us
Still have questions?
All our purifiers come with a 30-day, no-hassle money back guarantee, and are covered under a 1-3 year warranty (depending on your unit). HypoAir compact units cover very large areas of space. We rate our units' strength by square footage (sq. ft) coverage. These estimates are based on average contaminants found in a home. Some situations like smoking, large pets, or environmental dangers like mold infestations may require a unit with more power than the size of the location may indicate.
