Blue Pure 211 Particle + Carbon Filter
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.
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.
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.
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.
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.
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.
Since Blue Pure 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.
