The 8-Phase Austin Air Immunity Machine is their most comprehensive air purifier to date, made for individuals with heightened immune vulnerability, people living in new construction homes, and anyone exposed to modern chemical pollutants and viruses in high-traffic spaces like classrooms, clinics, and shared offices.
This next-generation air purifier uses eight different types of filtration media, including medical-grade and military-grade technology for advanced viral and chemical adsorption, removing the widest range of airborne threats. Because the Austin Air Immunity Machine uses mechanical filtration technology, it's safe for people with chemical sensitivities and respiratory conditions.
Unlike standard purifiers, which rely on one or two levels of protection, the Immunity Machine combines 8 types of filtration media to capture the widest range of airborne contaminants that weaken the immune system. From viruses, bacteria, mold spores, and allergens to toxic chemicals, VOCs, and gases, this purifier targets the most dangerous biological and chemical pollutants impacting human health. By removing the environmental stressors that compromise immunity, the Austin Air Immunity Machine sets a new standard in protection—delivering cleaner, healthier air than any other purifier on the market.
The Immunity Machine is part of a multi-unit bundle too! The Austin Air Immunity Machine filter is designed to last 5 years before it needs to be replaced.
More Carbon + Impregnated Zeolite!
The Austin Air Immunity Machine is engineered with four types of granulated adsorption media: carbon, impregnated carbon, zeolite, and impregnated zeolite. This four-part granular defense combo is designed to remove an unparalleled spectrum of airborne threats, from everyday VOCs, household chemicals, and odors to more aggressive pollutants like formaldehyde, sulfur compounds, ammonia, and harmful gases that standard purifiers miss. By blending traditional carbon and zeolite with their chemically enhanced, impregnated counterparts, the Immunity Machine provides a comprehensive defense against the pollutants most damaging to immune health. No other air purifier offers this level of filtration power, making it the most robust and effective solution on the market.
Military Grade Virus & Gas Filtration
Originally engineered for the British military to protect against chemical warfare, HEGA (High Efficiency Gas Adsorption) is a tightly woven carbon cloth with an extraordinarily high surface area. This powerful media not only captures volatile organic compounds (VOCs) and harmful gases, but it's also clinically proven to trap and deactivate airborne viruses*, making it an essential line of defense during viral outbreaks and flu seaso
