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.
