Blueair Blue Pure 311 Filter
Particle removing filtration, air cleaning carbon, all in one filter

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.


Blueair Blueair genuine filter
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.

Less noise and energy

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.

Minimizes unhealthy allergens and germs

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.

What is a filter subscription?

Purchasing a filter subscription saves you 15% on all future replacement filter orders + free shipping and extends your limited 1-year product warranty to an extended warranty for as long as you remain a subscriber. At the time of purchase, the subscription will automatically schedule filter deliveries at the recommended six months. You can always adjust this timeframe from the 'My Account' section.

How does this filter differ from the Blue Pure 311 Auto model?

While they look similar, our Blue Pure 311 is not the same air purifier as the Blue Pure 311 Auto, which features our upgraded auto-mode functionality and increased Clean Air Delivery Rate (CADR) performance. Due to the size difference, each respective model will have its own replacement filter and pre-filter accessories. All other features stay relatively the same.
