The SmartFilter comprises one particle filter layer and one active carbon filter layer. The activated carbon in the SmartFilter removes gas, odours, smoke, VOCs, exhaust, smog, and chemicals from the air.

The two parts of the SmartFilter are attached at the top, so when removing it, you can just fold it over like a booklet to keep dust and pollutants from escaping.

The built-in smart chip tracks the use of the filter and notifies you through the Blueair app when it is time to replace it. The SmartFilter must be replaced every 6 to 12 months, depending on your environment.

  • How often do I need to replace the SmartFilter?

    The air purifier calculates the remaining lifetime of the filter based on usage and sensor readings and shows when it is time to change the filter. The recommended time for filter change is between 6-12 months, depending on the indoor conditions. A filter replacement indicator appears on the control panel when it is time to change the filter.
