Intelligent, SmartFilter Technology
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.
Filter tracking ensures performance and efficiency
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.
Using genuine Blueair filters ensures that your purifier continues to work effectively — so your clean air, and your warranty, remain intact.
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.
After one year, the amount of time this filter is designed to last depending on room conditions, the Blueair app will let you know when it's time to reorder. It helps you with the purchase too!
The particle filter layer helps to minimize the airborne particles that can trigger allergy symptoms, including pollen, dust, mold spores, pet dander, viruses, bacteria, and fine smoke particles.
This filter’s extra large and absorbent surface of activated carbon removes chemicals, volatile organic compounds (VOCs), and annoying household odors from cooking, smoking, and pets.

Folds together during removal so the pollutants it traps won't get released back into the air. Filters high volumes of air while maintaining maximum airflow, and resists clogging.
This filter is equipped with a smart RFID chip that accurately monitors filter status. When a new filter is installed, it automatically resets the replace filter reminder so you're never left guessing.

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.
