Austin Air HealthMate Replacement Filter
Bring your purifier back to full strength with the genuine Austin Air HealthMate replacement filter. This single four-stage cartridge pairs true medical-grade HEPA with 15 lbs of activated carbon and zeolite to pull dust, pollen, smoke, odors, and everyday chemicals out of your air.
- Fits: all Austin Air HealthMate standard units (HM400 / B400).
- When to replace: rated for up to 5 years of normal residential use; refresh the pre-filter every ~6 months to protect it.
- Color: choose White (for White/Sandstone units) or Black (for Black/Midnight Blue units).
A note on buying ahead: this cartridge contains activated carbon, which slowly adsorbs odors and chemicals from the air around it even while sealed in storage. Order your replacement when you're ready to install it rather than keeping a spare on the shelf for years — carbon that has sat a long time won't have its full capacity left. Pre-filters aren't affected and are fine to keep on hand.
As an authorized Austin Air dealer, every Austin Air replacement 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.
