Designed for Optimal Performance
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.

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.
