Austin Air Healthmate HM400 Air Purifier — Physician-Recommended HEPA Filtration for 313 Sq Ft
Trusted by physicians and respiratory specialists worldwide, the Austin Air Healthmate HM400 is one of the most respected air purifiers on the market — and for good reason. Its 360° progressive filtration system draws air in from all directions, passing it through a hospital-grade HEPA filter and an outer carbon zeolite layer to remove 99.97% of micro-organisms, chemicals, gases, odors, allergens, and airborne particles larger than 0.3 microns. This is the air purifier doctors recommend — and now it's in your home.
6 Complete Air Changes Per Hour
In its recommended space of 313 square feet, the HM400 delivers an extraordinary 6 complete air changes every hour — meaning the air in your room is fully cycled and cleaned six times over in 60 minutes. That's the kind of continuous, thorough filtration that makes a real, noticeable difference in how your home feels and smells.
