Particle removing filtration & air cleaning, all in one filter
When used as part of our HEPASilent™ filtration process, the Particle 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.
To maintain optimum 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'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.

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.
