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, zeolite, and impregnated zeolite—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. 8 Phase Filtration The Austin Air Immunity Machine features an 8-phase filtration system—the most complete protection of any air purifier. Each type of filter media is engineered to remove specific pollutants that weaken the immune system. Phases 1 & 2: Prefilters – Capture visible dust, pet dander, pollen, and mold spores, keeping your air cleaner and the core filters working efficiently. Phases 3–6: A Four-Part Granular Defense Combo – A powerful blend of carbon, impregnated carbon, zeolite, and impregnated zeolite adsorbs odors, VOCs, formaldehyde, ammonia, nitrogen dioxide, and other harmful gases, providing unmatched chemical and gaseous pollutant protection. Phase 7: Medical-Grade HEPA – Removes 99.97% of airborne particles down to 0.3 microns and 99% down to 0.1 microns, including viruses, bacteria, allergens, and microplastics. Phase 8: HEGA Carbon Cloth – A military-grade filter originally designed for chemical, biological, and nuclear defense, eliminating the most dangerous ultra-fine contaminants. Together, these eight phases create the widest-ranging air purification system available, delivering cleaner, healthier air for optimal immune support.
