Austin Air Immunity Machine Replacement Filter

Maintain your Austin Air Immunity Machine Air Purifier or upgrade your existing air purifier with this advanced replacement filter engineered for individuals with heightened immune vulnerability, or exposed to modern chemical pollutants and viruses.  Made for Standard-size models, it restores optimal airflow and particle removal, helping you maintain a healthier indoor environment.

Featuring advanced eight-stage filtration technology, this filter is ideal for spaces where air quality impacts well-being, from new homes to busy offices. The different types of filtration media remove 99.97 percent of airborne particles down to 0.3 microns, reducing allergens and ultrafine debris that can irritate sensitive lungs. It incorporates fast-acting gas adsorption to capture viruses and bacteria on contact, supporting healthier air for immune-compromised individuals.

Upgrade Standard Models

Swapping this filter into any Austin Air standard-size cabinet instantly elevates performance to Immunity Machine levels. The process requires no tools beyond the hex key included with your purifier. Once installed, the enhanced media stack helps offset contamination often associated with renovation off-gassing, high-traffic classrooms and offices, or frequent patient turnover in medical clinics. By choosing one cartridge that addresses both particulate and chemical threats, you simplify inventory management while giving occupants cleaner, more breathable air day after day.
