How Long Will Filters Last?

The reason people buy air purifiers is to have healthier, cleaner air. Blueair is the very best unit in their room size capacity tested by AHAM (Association of Home Appliance Manufacturers) at providing clean air.

Blueair knows that an air purifier is only as effective as the filters. This is why, in order to maintain incredibly high levels of clean air, the filters in a Blueair 501 need to be changed twice a year.

Blueair feels that other manufacturers often make unrealistic claims about the life of their filters. And while a filter after a year or two may still be providing some level of filtration, it's not providing anything like the filtration you bought the unit for in the first place!

You may hear the unit running--but the filter has become so degraded after a year or two that what you're experiencing is the placebo effect—but not clean air.

Rather than tell you something that's not true, Blueair tells you how often the filters really need to be changed in order to maintain the specifications you bought the unit for in the first place.

Clearly, there is a monetary cost associated with clean air. Clean, healthy environments are what we're all about and Blueair would rather not sell you a unit than mislead you about what it takes to maintain the filtration and clean air you're expecting from us in the first place.

You may obtain replacement filters at the dealer you bought the unit from or direct from us at 800-417-1494 or here on our website. Blueair also offers a convenient Filter Subscription Program that automatically delivers the required filters every six months!
