Real-Time Filter Lifetime Status
Blueair’s proprietary RealTrack algorithm accurately calculates the remaining filter lifetime based on fan speed, usage time and pollution levels.
Quickly & Easily Change Your Filter
This air purifier features a hassle-free filter replacement system, allowing you to easily and quickly swap out the filter without any complicated procedures.

Less Noise and Energy
Blueair unique HEPASilent filtration technology allows this filter to be less dense, meaning it requires less air pressure. With it installed, your air purifier will operate more quietly while using less energy.
Keeps Clean Air Flowing, Resists Clogging
This filter's unique structure is designed to filter high volumes of air while trapping even the smallest particles. It maintains maximum airflow because it's engineered to resist clogging.
Minimizes Unhealthy Allergens and Germs
With the unique filter design at least 99.97% [3] of airborne particles, even down to 0.1 microns, are removed, while using less energy and producing less noise.
6 to 9 Month Filter Life
Accurate lifetime calculated using RealTrack. When the filter needs changing, the filter replacement LED will light up on the interface and the Blueair app will send you an alert.
