Austin Air HealthMate Plus Replacement Filter
Restore your purifier to full performance with the genuine Austin Air HealthMate Plus replacement filter. It builds on the standard 4-stage HEPA system with an enhanced activated carbon and zeolite blend impregnated with potassium iodide, targeting VOCs, formaldehyde, and a wider range of airborne chemicals and odors alongside dust, pollen, and smoke.
- Fits: all Austin Air HealthMate Plus units (HM450 / B450).
- 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).
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 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.
