Is this the right filter for you?
This filter is only compatible with the Blue Pure 121 air purifier, not the Blue Pure 211+. You can identify whether your air purifier is the 121 model, if it is 28.3” in height. The Blue Pure 211+ is 20” in height.
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.
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.
This filter's unique structure is designed to filter high volumes of air while trapping even the smallest particles. It maintains maximum airflow because it's engineered to resist clogging.
