Austin Air Filters and Accessories

These Austin Air Filters replacements and accessories are made specifically for our Austin Air air purifier collection. If your model HM400 was made or bought before the year 2000, you will need to purchase the HEGA FR405 (Austin Air Allergy Machine filter) filter for your unit.

Any units produced after the year 2000 can use any filter configuration, as the filters are all interchangeable (keep standard models HM400 with standard filters and junior models HM200 with junior filters).  

All filter packs include a pre filter, HEPA filter, and activated charcoal filter.  The pre filters are available separately as an option if you care to change more often. HEPA/Carbon filters are recommended to change every 4-5 years or sooner if necessary.
