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.

Blue pure 311 replacement filter.
Not as good a filter as the one that came with the unit. The original had blue tabs on the top. This one has white ones. ?

Thank you for sharing your observations, and I’m sorry for any confusion this may have caused. Please know that the replacement filter you received is indeed a genuine Blueair filter. The difference in tab color (blue vs. white) is simply due to packaging variations, both versions are authentic and fully compatible with your unit. We currently have two types of tabs used in production, but rest assured that the performance and quality of the filter remain the same as the original one that came with your unit.
