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 was made or bought before 1995, you will need to purchase the HEGA HM405 filter for your unit. Otherwise you can purchase any filter configuration you like, as the filters are all interchangeable (keep standard models with standard filters/ junior models 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.
