Is this the right filter for you?
This filter is only compatible with the Blue Pure 211+ air purifier (non-auto), not the Blue Pure 211+ Auto.
You can identify whether your air purifier is the standard 211+ non-auto version, if it has a button on the front of the air purifier. The 211+ Auto only has an LED light on the front.

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.
