FAQ
How do I know which filter size I need?
Check the label on your Austin Air unit — standard units begin with HM4 (like HM400), junior units start with HM2 (like HM200), and the personal "it" units are smaller and labeled accordingly.
Are Austin Air filters interchangeable?
Yes — but only within the same size category.
All standard-size filters fit all standard-size purifiers. So you can upgrade your filter (for example, from a HealthMate to a Bedroom Machine filter) without replacing your unit. Junior and “it” models require their own unique filter sizes.
Do I need a new filter when I buy a new Austin Air purifier?
No — every Austin Air purifier comes with a filter already installed and ready to use. You only need to purchase a replacement when it's time for a change, usually every 5 years.
Can I upgrade my current unit with a different filter type?
Absolutely. If you own a standard-size unit, you can switch to any other standard-size filter type — like the Bedroom Machine or HealthMate Plus — at any time. It’s an easy way to customize your purifier based on your current air quality needs.
How long do Austin Air filters last?
5 years under normal use — which makes them one of the longest-lasting filters on the market. In high-pollution or pet-heavy environments, you may choose to replace them sooner.
Do filters include the prefilter?
Yes — all Austin Air replacement filters come with the main filter and integrated prefilter layers. You do not need to purchase the prefilter separately unless you’re just replacing that component.
