Standard Austin Air Filters
What makes Austin Air filters the best?
- Superior value. In addition to initial cost, you can save thousands of dollars in filter replacements over the lifetime of your purifier: Austin Air main filters only need to be replaced once every 5 years!
- True HEPA. Austin Air uses true medical-grade HEPA filters in every purifier: 60 square feet in standard size machines and 30 square feet in Junior sizes.
Note: All Austin Air main filters are interchangeable! Any Austin Air replacement filter will fit in your existing machine. Just make sure the size of the filter matches your unit (Standard or Junior size).
