Austin Air Allergy Machine Replacement Filter

Genuine Austin Air Allergy Machine replacement filter featuring HEGA (High Efficiency Gas Absorption) carbon-cloth technology paired with medical-grade HEPA. Designed for allergy and asthma sufferers, it captures fine particles and allergens while the activated carbon cloth absorbs gaseous irritants and odors.

  • Fits: Austin Air Allergy Machine units (HM405 / B405).
  • 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.
