Look-a-likes don't stand a chance
Genuine Blueair filters are specifically designed to enable more air flow through the filter media. When combined with electrostatic filtration this results in faster cleaning than traditional HEPA filtration.
Using genuine Blueair filters ensures that your purifier continues to work effectively — so your clean air, and your warranty, remain intact.
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.
Once made, the only thing this fully recyclable filter adds back to the environment is clean air. Check your local recycling facilities for availability and further guidance.
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.
