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.
