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. 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.
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.
Filter fibers resist bacteria and mold growth, to ensure you'll never put bacteria and mold back into the air.
This filter is 100% recyclable, so the only thing you're adding back into the environment is clean air.
To maintain optimum performance, we recommend changing your filter about once every 6-months when used 24 hours a day.
The filter structure traps even the smallest particles and resists clogging to maintain maximum airflow.

This filter is compatible with the original Blue 211 model.
Purchasing a filter subscription saves you time and effort. At the time of purchase, the subscription will automatically schedule filter deliveries at the recommended six months. You can always adjust this timeframe from the 'My Account' section.
Since Blue 211 and 221 models look alike, you may need the model number to tell them apart. The original 211 model uses the following serial number prefaces: CB211, CBA211, KDL211, 211. You can also identify the 211 by the single piece filter and diamond-pattern metal cage.
Upgrading to the 221 model replaces the disposable metal filter frame with a durable, reusable metal housing to eliminate unnecessary plastic waste. Upgraded replacement filters are collapsible for added space-saving storage.
