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.
Unlike generic look-a-likes, genuine Blueair replacement filters are specifically designed to maintain superior performance over time and ensures your warranty remains intact.
When it's time to replace your filter (about every six months), start by unplugging your air purifier. Open the front door to remove the old filter and vacuum away any dust on the inside. Insert the replacement filter, close the door, and plug back in. Easy.
Orders ship free and typically arrive within 5 business days in most states. Charges may be incurred for Alaska and Hawaii.
Breathe easy with a 60-day in-home trial period. If you're not happy, we'll help arrange for a free return.
Guarantee clean air for years to come by extending your 1-year warranty coverage for up to 5-years.
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 gradient filter structure traps even the smallest particles and resists clogging to maintain maximum airflow.
This filter is recyclable, so the only thing you're adding back into the environment is clean air.
Filter fibers naturally 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.

This filter is compatible with the following Classic 301 model.
No, Blueair filters are less dense than traditional HEPA filters, allowing our air purifiers to be quieter and more energy-efficient. Instead of HEPA filters, we use a combination of electrostatic and mechanical filtration that we call HEPASilent™ technology to achieve the same level of filtration efficiency as 'True HEPA' - with less energy and noise.
