Austin Air Immunity Machine Replacement Filter

Upgrade your Austin Air to its strongest level of protection.
The Austin Air Immunity Machine Filter brings the same advanced 8-phase filtration found in the Immunity Machine to any standard full-size Austin Air housing.

This replacement filter captures the widest range of biological and chemical pollutants ever addressed by a home air purifier — including VOCs, formaldehyde, mold spores, bacteria, and aerosolized viruses as small as 0.1 microns.

Designed for people with autoimmune issues, multiple chemical sensitivity (MCS), or those who live in newly built or renovated homes, this filter provides professional-grade protection with medical-grade materials.

Every filter is made using solid steel framing and certified medical-grade HEPA materials — never plastic.
