Blueair Blue Pure 311 Filter

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.

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.

¹A flat shipping rate of $25.00 will be charged on filter shipments to Alaska and Hawaii. Additional charges may apply for shipments over 30 lbs.
