Blueair's proprietary RealTrack algorithm accurately calculates the remaining filter lifetime based on fan speed, usage time and pollution levels.
Depending on usage, your filter will last up to 9 months.
It’s important to change your filter when needed because dirty filters clean the air less efficiently, reducing the purifier's ability to capture pollutants and affecting overall air quality in your space.
