Medical-Grade HEPA & Carbon Replacement Filter for HealthMate Air Purifiers
Austin Air Immunity Machine 8-Phase Air Purifier
The Austin Air Immunity Machine has the most complete filtration system Austin Air has ever built. It's made for people with weakened immune systems, households in newly built or renovated homes, and busy shared spaces like classrooms, clinics, and offices where viruses and chemical pollutants build up.
Eight filter layers work together inside one 5-year filter. Two prefilters catch dust, hair, pet dander, pollen, and mold spores. Four layers of granular media pull out odors, VOCs, formaldehyde, ammonia, and nitrogen dioxide from gas appliances: activated carbon, chemically treated carbon, mineral-based media, and treated mineral media. Medical-grade HEPA and military-grade HEGA carbon cloth then finish the job on fine particles, viruses, and gases.
Air is pulled in from every side through a 360° perforated steel housing. The unit uses only mechanical filtration, with no ozone and no ionization, so it's a safe choice for people with chemical sensitivities or breathing issues. Every unit is handcrafted in Buffalo, New York.

"Immunity Machine for Healthier Homes
the Austin Air Standard Immunity Unit (Immunity Machine) is a heavy-duty room air purifier designed for people who want maximum protection against airborne irritants and contaminants. It uses multi-stage filtration, combining a True HEPA filter that captures 99.97% of particles down to 0.3 microns with a deep bed of activated carbon (and zeolite) to help reduce odors, chemical fumes, and gases along with dust, pollen, pet dander, smoke, and mold spores. Its 360-degree air intake pulls in air from every direction, and the steel-cased build is made for continuous, long-term use in bedrooms, living areas, and offices. It’s a strong choice for households managing allergies, sensitivities, or immune-related concerns, or anyone who wants dependable, hospital-grade-style air cleaning day after day.
Why Austin Air Purifiers Are a Smart Choice
Austin Air has been building medical-grade air purifiers by hand in Buffalo, NY since 1990. They're trusted by hospitals, schools, first responders, and families in more than 100 countries.
- Medical-grade filtration: Every unit pairs 60 sq. ft. of true HEPA with up to 15 lbs. of activated carbon and zeolite to capture fine particles like dust, pollen, mold spores, and smoke, plus the VOCs, chemical fumes, and odors that standard HEPA filters miss.
- Filters that last up to 5 years: Most purifiers need new filters every few months. Austin Air filters are designed to go about five years before replacement, which keeps upkeep simple and saves money over time.
- Built like a tank: A heavy-duty steel housing and 360° air intake mean these units run around the clock for years, pulling air in from every side of the room.
