The Austin Air Allergy Machine air purifier (HM405) was designed to offer allergy and asthma sufferers’ maximum air filtration for the reduction of symptoms associated with pollen, pet dander, dust and other allergens. Integrating a military grade carbon cloth with a HEPA media, the HM405 provides high efficiency absorption of harmful gas contaminants and 99.97% of all particles down to 0.3 microns. Perfect for large spaces up to 1500 square feet, the powerful Allergy Machine HM405 can change out the air in the room up to 2 times per hour with minimal energy consumption. Safe and effective, the HM405 provides you with healthier, cleaner air without producing any harmful ozone.

The Austin Air Allergy air purifier HM405 surpasses other air purifiers at cleaning the air because of the 360º air intake system which allows 250 cubic feet of air passes through the unit every minute. Made of 22 gauge steel, the perforated intake system draws air in from all four sides of the unit. The air is then purified utilizing a 4 stage filter that progressively removes contaminants from the air. In stage 1, a large particle pre-filter captures particles visible to the naked eye like hair, dust and pet dander. In stage 2, a medium particle pre-filter removes small to medium particles like mold spore, pollen, bacteria and viruses. In Stage 3, 60 square feet of certified true medical HEPA, the most effective filtering media available, removes 99.97% of all particles down to 0.3 microns and 95% down to 0.1 microns. Stage 4 utilizes activated military grade carbon cloth to remove odors from pets, smoke, tobacco, gases and other VOC’s. For the most efficient air purification, make sure to run your HM405 on high for the first four hours of use and allow for at least a 4” clearance from walls and/or furniture for maximum filtration.

The HM405 requires very little maintenance. Vacuum the surface with a brush attachment to remove any dust buildup around the air intake area. Other surfaces can be cleaned with a damp cloth.
