Blueair Particle + Carbon Replacement Filter for Blue Pure Air Purifier

This replacement filter is specifically designed for the Blue Pure 211+ Auto and the Blue Pure MAX air purifiers. It will not fit other Blueair models, so please verify your unit's model number before purchasing.

Blueair recommends replacing the filter every six months, or approximately 4,380 hours of use. If you live in an area with high pollution or run the unit constantly, you may notice the filter needs changing sooner to maintain optimal airflow.

This rating indicates the filter's ability to capture extremely fine particles, including smoke, bacteria, and viruses. By trapping particles as small as 0.1 microns with 99.97% efficiency, it provides a much higher level of filtration than standard filters that only target larger dust or pet dander.

Using genuine Blueair filters is recommended to maintain your air purifier's warranty and ensure the device performs as intended. Third-party filters often lack the specific gradient structure and antibacterial fiber density required to match Blueair's airflow and filtration standards.

Yes, this filter is 100% recyclable. Once you have replaced it, you can check your local recycling guidelines to dispose of the materials responsibly.
