Austin Air Bedroom Machine Replacement Filter (FR402)
The FR402 is the genuine Austin Air replacement filter for the Bedroom Machine (HM402). It restores the Bedroom Machine's full 5-stage filtration—including the extra HEGA carbon-cloth layer—so your unit returns to the quiet, thorough performance it had when new. This is a genuine Austin Air filter (not an aftermarket copy).
What's in the filter
A single cartridge carrying all five stages: large- and medium-particle pre-filters; a deep bed of activated carbon and zeolite; 60 sq ft of True Medical-Grade HEPA; and the Bedroom Machine's signature HEGA carbon-cloth layer for extra capture of ultra-fine particles and gases.
Compatibility — does it fit my unit?
- Genuine part number: FR402
- Fits: Austin Air Bedroom Machine (model HM402)
- Colors: Black (for Black & Midnight Blue units) and White (for White & Sandstone units)—identical media; color only matches your cabinet
- Not interchangeable with the HealthMate (FR400) or Plus (FR450) filters—the Bedroom Machine's 5-stage filter includes the HEGA cloth those don't have
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, chemical, or dust exposure.
Why choose the genuine filter
- Exact fit and a proper pressure seal, so all the air passes through the media
- Includes the HEGA carbon-cloth stage—the whole reason the Bedroom Machine filters more than a standard HealthMate
- Keeps your Austin Air warranty intact
