Is this the right filter for you?
This filter is only compatible with the Blue Pure 211+ Auto air purifier, not the standard Blue Pure 211+ (non-auto).
You can identify whether your air purifier is the standard 211+ non-auto version, if it has a button on the front of the air purifier. The 211+ Auto only has an LED light on the front.
Particle removing filtration, air cleaning carbon, all in one filter
When used as part of our HEPASilent™ filtration process, the Particle + Carbon filter provides protection against odors, chemicals, gases and 99.97%* of airborne pollen, dust and germs*.
Keep your filter fresh and pollutants at bay
We recommend replacing your air purifier filter about every 6 months (when used 24 hours a day). That's because, just like a vacuum cleaner, over time air purifier filters can get clogged with pollutants, and even let unpleasant odors back into the room.
It's simple to replace in just a few quick steps, and easy to save with our filter subscription program.
Our unique HEPASilent™ filtration technology allows this filter to be less dense, meaning it requires less air pressure. With it installed, your air purifier will operate quieter while using less energy.
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.
This filter's unique structure is designed to filter high volumes of air while trapping even the smallest particles. It maintains maximum airflow because it's engineered to resist clogging.
To maintain optimal performance, we recommend changing your filter about once every 6-months when used 24 hours a day. Don't forget to save with our subscription program.

This filter is compatible with the Blue Pure 211+ Auto model only. If used with the standard Blue Pure 211+ model 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.

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.
