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.
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.
Unlike generic look-a-likes, this genuine Blueair replacement filter is specifically designed to maintain premium performance over time.
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.
Designed to last for a maximum of one year depending on room conditions. When it's time to replace the filter, the Blueair app will send you an alert and allow you to re-order at the touch of a button.
Removes airborne pollutants and allergens such as pollen, dust, pet dander, mold spores, fine smoke particles and more. Blueair purifiers are not tested against SARS-CoV-2 (COVID-19).
Activated coconut carbon has a large adsorbent surface area to effectively remove chemicals, Volatile Organic Compounds (VOC), and annoying household odors from cooking, smoke, and pets.
This filter is recyclable, so the only thing you're adding back into the environment is clean air. Please check your local recycling facilities for availability.
The book-like design maximizes the filter surface area and helps to prevent premature clogging. Folds together like a book to minimize exposure to pollutants during replacement.
Equipped with a smart RFID chip to accurately monitor filter status and automatically reset the replace filter reminder when a new filter is installed.

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.
