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.

Blueair purifiers are not tested against SARS-CoV-2 (COVID-19).

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.

Genuine performance, superior quality

Unlike generic look-a-likes, genuine Blueair replacement filters are specifically designed to maintain superior performance over time and ensure your warranty remains intact.

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.

What Blueair models are compatible with this filter?

This filter is compatible with the following Protect family models: 7710i, 7770i.

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.

Is it dangerous to use the filters for longer than recommended?

Using filters which are filled with dust or saturated with odors will not bring dangerous components to your home. But if the filter is full, it may be difficult for the clean air to come out and it might damage the air purifier in the long run. For best results and to guarantee a valid warranty, we recommend changing the filters according to the indications.
