Blue Pure 211 Particle + Carbon Filter
Add to cart options
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.
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.
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.
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 gradient filter structure traps even the smallest particles and resists clogging to maintain maximum airflow.

Since Blue Pure 211 and 211+ 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 latest version of the 211 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.
