Full Product Details
Austin Air HealthMate Plus Replacement Filter (FR450)
The FR450 is the genuine Austin Air replacement filter for the HealthMate Plus (HM450). It restores the Plus's enhanced 4-stage filtration—Medical-Grade HEPA plus a specialized carbon blend built for chemicals, VOCs, formaldehyde, and smoke—so your unit performs like new. This is a genuine Austin Air filter (not an aftermarket copy), which matters for fit, the pressure seal, and rated performance.
What's in the filter
A single cartridge carrying all four stages: a large-particle pre-filter and medium-particle pre-filter; a deep bed of activated carbon, potassium-iodide impregnated carbon, and zeolite tuned for VOCs, formaldehyde, and chemical odors; and 60 sq ft of True Medical-Grade HEPA for fine particles. It's the same media that makes the Plus better than the standard HealthMate for smoke and chemicals.
Compatibility — does it fit my unit?
- Genuine part number: FR450
- Fits: Austin Air HealthMate Plus, full-size (model HM450)
- Colors: Black (for Black & Midnight Blue units) and White (for White & Sandstone units)—identical internal media; color only matches your cabinet
- Not interchangeable with the standard HealthMate (FR400), Junior (FR200), Plus Junior (FR250), Bedroom Machine (FR402), or Immunity (FR444) filters
When to replace it
Austin Air rates the filter for up to 5 years under normal residential use (pro-rated 5-year filter warranty). Replace sooner with heavy smoke, construction dust, or strong chemical loads, or if odors and airflow start to slip.
Why choose the genuine filter
- Exact fit and a proper pressure seal, so all the air passes through the media
- The full specialized carbon blend—the whole point of the Plus—not a reduced-media substitute
- Keeps your Austin Air warranty intact
Frequently asked questions
How often should I replace it?
About every 5 years for a typical home; sooner with heavy smoke, chemical, or dust exposure.
What's included?
One complete 4-stage HealthMate Plus cartridge (pre-filters + specialized carbon/zeolite + Medical HEPA), in Black or White.
Is this different from the standard HealthMate filter?
Yes. The FR450 uses the Plus's enhanced carbon blend (including potassium-iodide impregnated carbon) for chemicals and VOCs; the standard HealthMate filter (FR400) does not.
Will it fit my HealthMate Plus Junior?
No—the Plus Junior is a smaller unit and uses the FR250.
