Austin Air Replacement Immunity Machine Filter (Immunity Machine) - FR444

The Austin Air Immunity Machine Replacement Filter brings the power of our most advanced 8-phase filtration system to your existing standard model purifier. Engineered for individuals with heightened immune vulnerability, those living in new construction homes, or anyone exposed to modern chemical pollutants and viruses in high-traffic spaces like classrooms, clinics, and shared offices, this replacement filter upgrades your current unit to next-level protection.

This next-generation filter combines eight different types of filtration media—including medical-grade HEPA, military-grade HEGA carbon, and a four-part granular defense combo of carbon, impregnated carbon, mineral-based filtration, and impregnated mineral-based filtration—to remove the widest range of airborne threats.

Unlike traditional filters that primarily target particles, the Immunity Machine Replacement Filter is designed to capture and neutralize gases, VOCs, viruses, bacteria, and ultrafine particles, ensuring your air purifier continues to deliver comprehensive immune-supporting protection for your home or office.
