Introducing Blueair SmartFilters

Our most advanced filter technology, SmartFilters are designed to deliver superior performance with data-based filter lifetime tracking, a smart RFID chip, and longer filter life (maximum of 1 year). A particle filter layer removes airborne particles like pollen, dust, mold spores, pet dander, viruses and bacteria, and smoke particles, while activated carbon throughout the filter absorbs gases, Volatile Organic Compounds (VOC), chemicals, and odors.


Protect 7400 series shown to remove 99.99% of airborne SARS-CoV-2 in a 13 ft³ test chamber. Not proven to kill/prevent transmission of SARS-CoV-2 (COVID-19). Other Blueair purifiers have not been tested against SARS-CoV-2.

Accurate tracking

Helps you get the most out of your filter and eliminate unnecessary replacement with an algorithm to calculate filter life based on fan speed, particle sensor data, and estimated filter loading. View data anytime via the app.

Booklet design

Our Swedish heritage inspires us to put quality at the heart of everything we do. The booklet design of the SmartFilter means you can easily remove them from your air purifier while trapping in pollutants so they aren't released back into the air.

Are Blueair filters HEPA?

No, Blueair filters are less dense than traditional HEPA filters, allowing our air purifiers to be quieter and more energy-efficient. Instead of HEPA filters, we use a combination of electrostatic and mechanical filtration that we call HEPASilent™ technology to achieve the same level of filtration efficiency - with less energy and noise.
