Austin Air Immunity Machine – Medical-Grade Protection for a Healthier Home

If you're concerned about viruses, mold, chemicals, or poor indoor air quality, you’re not alone. The air inside most homes can contain allergens, VOCs, mold spores, and airborne pathogens that quietly undermine health—especially for people with chemical sensitivities, asthma, allergies, or compromised immune systems. The Austin Air Immunity Machine was designed specifically to address these concerns with medical-grade HEPA filtration and powerful air purification that helps create a truly healthy, non-toxic indoor environment.

Unlike typical air purifiers that focus only on dust and pollen, the 8-Phase Immunity Machine goes much further. Its true medical-grade HEPA filter combined with military-grade carbon filtration captures and removes viruses, bacteria, mold spores, allergens, smoke, VOCs, and airborne chemicals. The result is cleaner, healthier air that supports stronger respiratory health and better indoor air quality—a critical step toward creating a safe, low-toxin home.

We sell replacement filters and pre-filters for this unit. Filters should be changed every 4-5 years (depending on hours of usage, fan speed, and degree of air pollution).

At Green Building Supply, we recommend products that are high-performance, durable, and safe for chemically sensitive individuals. The Austin Air Immunity Machine meets those standards with no ozone output, no ionization, and no off-gassing of plastics. It is made of robust steel construction with very long-lasting filtration media. It’s a dependable solution for families seeking non-toxic air purification and long-term protection from airborne contaminants.
