Austin Air Immunity Machine Replacement Filter

Genuine Austin Air Immunity Machine replacement filter — the highest-capacity filter in the Austin Air lineup. It combines medical-grade HEPA with a large activated carbon and zeolite bed for comprehensive removal of particles, bioaerosols, odors, and chemicals in demanding environments.

  • Fits: Austin Air Immunity Machine units (B444).
  • When to replace: rated for up to 5 years of normal residential use; refresh the pre-filter every ~6 months to protect it.
  • Choose your color: White (White/Sandstone units) or Black (Black/Midnight Blue units).

As an authorized Austin Air dealer, every filter we ship is genuine OEM — sealed and sized to Austin's clinically tested spec, so you won't lose efficiency to the air-leak issues common with third-party filters.
