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. Gently press the release buttons on either side until you hear a click, and lift off the top. Remove the old filter and replace it with a new one. Replace the top portion of the air purifier -it will click when it's in place- and plug back in. Easy.

Less dense filters make the difference

Our unique HEPASilent™ filtration technology allows our filters to be less dense. Less dense filters require less air pressure— resulting in quieter and more energy efficient air purifiers.

Remove allergens & germs

The particle filter layer helps to minimize the airborne particles that can trigger allergy symptoms, including pollen, dust, mold spores, pet dander, viruses, bacteria, and fine smoke particles.

Remove household odors

A layer of activated coconut carbon absorbs light gases, including volatile organic compounds (VOC), smog, chemicals, and annoying household odors from pets, smoke, and cooking.

6-month filter life

To maintain optimum performance, we recommend changing your filter about once every 6-months when used 24 hours a day.
