Replacement filter for the Austin Air Immunity Machine Air Purifier. Also compatible with "ALL" other 400, 402, 405 and 450 Series Austin Air Purifiers. Upgrade your current filtration system by switching to the Immunity Machine Replacement Filter.

Removes 99.97% of all particles down to 0.3 microns in size.
Removes 99% of all particles down to 0.1 microns, including viruses, bacteria, PM2.5, and microplastics.

Uses a powerful, eight phase filtration system designed to eliminate the widest range of airborne threats impacting the human immune system—from allergens and mold spores to viruses, chemicals, and toxic gases. Here's what happens as air flows through each filtration layer:

Phase 1: Large Particle Prefilter
First Defense Barrier – This initial phase captures visible pollutants like dust, hair and pet dander—keeping the rest of the system running efficiently and your air noticeably cleaner.
Phase 2: Medium Particle Prefilter
Removes smaller irritants like mold spores and pollen that often trigger allergies, especially in children and sensitive individuals.
Phase 3: Activated Carbon
Odor & Gas Adsorber – This filtration tier uses granulated activated carbon to eliminate odors from pets, cooking, and smoke, while also removing common gases and chemicals.
Phase 4: Potassium Iodide-Impregnated Carbon
Advanced Chemical Component – This enhanced carbon phase neutralizes specific hazardous chemicals like formaldehyde, VOCs, and other byproducts of wildfire smoke, building materials, and household cleaners.
Phase 5: Zeolite
Dedicated Detox Agent – A unique segment of the system, our granulated zeolite adsorbs specific gases like ammonia and helps detoxify air in ways carbon alone can’t.
Phase 6: Proprietary-Impregnated Zeolite
Enhanced Gas Neutralizer – This fortified zeolite binds to nitrogen-based gases such as Nitrogen Dioxide (NO2) found in smog and emitted from gas appliances, as well as other difficult-to-remove pollutants.
Phase 7: Medical Grade HEPA
Medical-Grade Particle Protection – A medical-grade filtration element, this HEPA material removes 99.97% of airborne particles down to 0.3 microns and 99% of particles down to 0.1 microns—including bacteria, viruses, microplastics, and allergens.
Phase 8: Military-Grade HEGA (High-Efficiency Gas Adsorption)
Military-Strength CBRN Blocker – This advanced filtering section uses a military grade HEGA carbon cloth that’s also used in military clothing to protect against chemical, biological, radioactive, and nuclear (CBRN) agents, removing dangerous gases, viruses, and ultra-fine contaminants from the air.

The Austin Air Immunity Machine filter is designed to last 5 years before it needs to be replaced.
