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.
