Locate Your Austin Air Model Number

When you need a replacement filter, knob, cord, or another part for your Austin Air air filter, the best place to start is with the model number. This will keep you from having to guess at what might or might not fit in your machine--a method that often results in the wrong parts arriving in the mail. If you still have the owner’s manual or box that came with your filter, you can find the model number there. If not, you’ll need to search a bit on your filter to find the information you need.

Austin Air most commonly places the model number on a medium-sized sticker on the back of their units. You may also want to search on the sides, and in some cases just inside the air screen to find the model number. Look for a combination of letters and numbers such as HM405, HM410, and so on. Once you find that number, just enter it into the search box located at the top of this page to bring up a list of parts specific to your air filter.

If you’re still having trouble finding that number, don’t worry. Just give us a call and we’ll happily help you find the information you need for your fix.

Family Knows Best
Austin Air is, at its core, a family company. After years of having doctors and specialists tell his wife that there wasn’t much they could do for her respiratory issues, the company’s president designed a filter that could get the job done better than medication--and a week later his wife was sleeping through the nights.

The true-HEPA, carbon filters help create the clean, crisp air everyone should enjoy in their homes. Whether you need a unit for your room, the baby’s room, or just to help get rid of all that pet hair, Austin Air has a product that will have you breathing wonderful fresh air in no time.
