About the Blueair - Blue Pure 221 Particle + Carbon Filter
A winning combination
The combination particle + carbon filter removes annoying household odors, chemicals, and gases, as well as 99.97% of airborne particles, like pollen, dust, viruses, and more with Blueair’s HEPASilent™ filtration technology.
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.
Features of the Blue Pure 221 Particle + Carbon Filter
- 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.
Traps particles for good - The filter structure traps even the smallest particles and resists clogging to maintain maximum airflow.
