Smart filters

Blueair’s most advanced filter, SmartFilter is designed to deliver superior performance. One particle filter layer and one active carbon filter layer combine to remove gas, odors, smoke, VOCs, exhaust, smog, and chemicals from the air. Designed with a booklet style frame, so when removing the filters, you can just fold them over like a booklet to keep dust and pollutants from escaping. Equipped with a smart RFID chip to accurately monitor filter status and automatically reset the replace filter reminder when a new filter is installed.

Less dense filters make the difference

Our unique HEPASilent™ filtration technology allows our filters to be less dense. Less dense filters require less air pressure— resulting in quieter and more energy efficient air purifiers.

Minimizes unhealthy allergens and germs*

Can I vacuum or wash the filters to use them longer?

It is not recommended to clean the filters in any way. Vacuuming or washing filters with water could damage the filter media and decrease the performance. 

Can I use the filters if the cardboard around the filter is removed or damaged?

The cardboard is part of the filter and ensures that there is no air leakage. The efficiency of the filter may decrease if the cardboard has been removed or is damaged. If you have any doubts about the state of your filter, please contact the Customer Support teams.
