Protect 7400 Series SmartFilter

SmartFilters pair superior performance with longer life engineering and data-based, RFID chip powered usage tracking. All in a single filter.Delivers dual protection with a particle filter layer that removes pollen, dust, mold spores, pet dander, smoke, bacteria and virus particles (including 99.9% of SARS COV-2 COVID-19*), while activated carbon throughout the filter absorbs gases, Volatile Organic Compounds (VOCs), chemicals, and odors.*Protect 7470i was tested in a 13ft³ test chamber. Performance may vary depending upon the room size and location of the device within the room, quantity of particulates in the air, and product use pattern (operational settings and use duration, etc.). Not proven to prevent/reduce transmission of COVID-19.

Just like a vacuum cleaner, over time air purifier filters can get clogged with pollutants, and even let unpleasant odors back into the room.To ensure your don't change your filter too late or too soon, the SmartFilter uses an algorithm to calculate filter life based on fan speed, particle sensor data, and estimated filter loading - so you can accurately see how much life your filter has left, and will get a reminder when it needs replacing (up to a maximum of one year).It's simple to replace in just a few quick steps, and easy to order with our app and save with our filter subscription program.

Genuine Blueair filters are specifically designed to enable more air flow through the filter media. When combined with electrostatic filtration this results in faster cleaning than traditional HEPA filtration.

Our Swedish heritage inspired the simplicity and effectiveness of this filter's booklet design. When inside the air purifier it maximizes the filter surface area, and upon removal, it folds together like a book - trapping pollutants so they are not released back into your air.
