Replacement Filter

The Air Cleaner Store offers free shipping to 48 States on Austin Air replacement filters. All standard size replacement filters are interchangeable if your air cleaner was built after 1995*. If your Austin Air machine was made in 1995 or earlier, use the Allergy Machine™ replacement filter. If you are unsure, contact us with your serial number and we will let you know which filters will work.

We suggest changing filters every 3 – 5 years. Austin Air filters have a 5 year prorated warrantee.
