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. Open the back door to remove the old filter and vacuum away any dust on the inside. Insert the replacement filter, close the back door, and plug back in. Easy.
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.
Particle filter removes airborne pollutants and allergens such as pollen, dust, pet dander, mold spores, bacteria, viruses, fine smoke particles, and more.
The filter structure traps even the smallest particles and resists clogging to maintain maximum airflow.
This filter is 100% recyclable, so the only thing you're adding back into the environment is clean air.
Filter fibers resist bacteria and mold growth, to ensure you'll never put bacteria and mold back into the air.
To maintain optimum performance, we recommend changing your filter about once every 6-months when used 24 hours a day.
