This includes activated carbon, impregnated carbon, Mineral-Based Filtration, and impregnated Mineral-Based Filtration — working together to adsorb the widest range of gases, odors, and chemical compounds.

By targeting the pollutants that can make indoor environments feel heavy or stale, the Immunity Machine helps create a cleaner, fresher space to support your comfort and peace of mind. It’s the next level of air purification for families who want an environment that feels lighter, clearer, and easier to breathe in every day.
Filter Designed To LastFive Years
Military-Grade HEGA Carbon Cloth
The air inside our homes often carries more than just dust and pollen. Everyday products like paints, cleaners, furniture, and even building materials can release gases and chemicals into the air. Over time, these substances may build up indoors, leaving the air feeling less fresh and comfortable. That’s why it’s important to have an air purifier designed to reduce not only particles but also these invisible airborne pollutants.
The Austin Air Immunity Machine is equipped with a layer of military-grade HEGA carbon cloth, originally developed for use in chemical warfare. This advanced material works alongside a substantial amount of activated carbon and Mineral-Based Filtration to adsorb a wide range of gases, odors, and chemical compounds. The result is cleaner, fresher air in your home — giving you and your family the confidence that the air you breathe feels lighter, clearer, and more refreshing.
