Replacement Filters for Air Purifiers

At the heart of every air purifier is an air filtration system. This filtration system ensures that your air purifier maintains top performance to deliver refreshing, clean air throughout your home. Although some air purifiers feature permanent filters or even filterless designs, most have air filters that need to be replaced periodically.

Whether you are looking for replacement HEPA filters, carbon filters, pre-filters, or replacement filter packs, we have the right air filter replacement to suit your needs. You can easily browse our selection of air purifier replacement filters by selecting your air purifier brand and model from the drop-down menu.

To receive convenient email reminders when it is time to replace your air purifier filters, sign up for our Better Air Program. As part of our Better Air Program, you will also receive members-only discounts toward your purchase of replacement air filters.

More About Air Purifier Filters

Although most air purifier filter systems contain similar elements such as a pre-filter, HEPA filter, and an odor-absorbing filter, each filter is designed to fit a specific air purifier model. We carry a wide variety of air purifier replacement filters to ensure that you can find just the right one for your air treatment system.

If you have a multi-filter air treatment system, such as those in IQ Air purifiers, Austin Air purifiers, and Rabbit Air purifiers, we offer complete collections of replacement air filters for these popular brands and many more to help maintain optimal performance in your air purifier. For industrial air scrubbers, like those from Phoenix, we have air filter replacements that help clean the air in large spaces quickly and efficiently.
