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.
This filter is recyclable, so the only thing you're adding back into the environment is clean air. Please check your local recycling facilities for availability.
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 Blue Pure 211+ Auto model only. If used with the standard Blue Pure 211+ model or Blue Pure MAX, the clean air delivery rate (CADR) will decline.
If the position of the main button is on the top of the air purifier, you have a 211+ Auto model and this filter is compatible.
Purchasing a filter subscription saves you 15% on all future replacement filter orders + free shipping and extends your limited 1-year product warranty to a lifetime warranty for as long as you remain a subscriber. 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.
Often, the weight of carbon in a filter is considered when evaluating an air purifier’s ability to remove smoke-related pollutants from the air. While the presence of activated carbon is important to neutralizing odor, the efficiency and airflow of the air purifier should also be considered. This is because smoke from tobacco, wildfires and other sources contains fine particles, harmful chemicals and volatile organic compounds (VOC), as well as annoying odors.
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 - with less energy and noise.
