When used as part of our HEPASilent™ filtration process, the Particle + Carbon 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.

FAQ

What Blueair air purifier is compatible with this filter?

This filter is compatible with the Blue Pure 311 air purifier.

How do I reset my filter replacement indicator (red light) on my Blue Pure air purifier?

A red filter replacement indicator appears on the air purifier when it is time to change filter, after about 6 months of operation.

After you replace your filter, press the center button down to reset the filter light indicator until the red light disappears. It usually takes 7-10 seconds and may take up to 30 seconds depending on the model.
