Uncompromised particle removal
Particle filters minimize allergy triggers, viruses, and bacteria for a healthier home environment with high filtration efficiency. Together with HEPASilent� filtration technology, our particle filters remove 99.97% of airborne particles down to 0.1 microns, including pollutants such as pollen, dust, pet dander, mold spores, viruses, bacteria, fine smoke particles and more.

Genuine performance, superior quality
Unlike generic look-a-likes, genuine Blueair replacement filters are specifically designed to maintain superior performance over time and ensures your warranty remains intact.

Replacement is easy
When it's time to replace your filter (about every six months), start by unplugging your air purifier. Lift the lid and remove the top filter and then each of the side filters. Insert the replacement filters on the sides first and then the top filter. Replace the lid and plug back in. Easy.
