Rids homes of pollutants and odors 4x faster⁰
Pure, high-porosity coconut carbon is 4x faster⁰
than our other filters at removing gaseous pollutan
ts, household chemicals and cleaners, volatile organic compounds (VOCs) and pet, smoking, and cooking odors.
When used as part of our HEPASilent™ filtration process, the DualProtection filter also efficiently removes 99.97% of airborne pollen, dust, mold*, germs and fine smoke particles.
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.
Classic DualProtection filters feature a highly-porous, lightweight carbon mesh that is extremely efficient at removing both particle and gaseous (odors, exhaust, smoke odors, and chemicals) pollutants from the air. Whereas Classic Particle filters are highly efficient in the removal of particle pollutants like pollen, dust, mold*, viruses*, 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 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.
Every aspect of this filter is engineered for wellness. It uses only pure, high-porosity coconut carbon to remove gases and odors. Filter fibers also resist bacteria and mold growth.

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.
