The gradient filter structure resembles many filters in one, trapping particles of all sizes while maintaining maximum airflow. The progressive structure resists clogging and won’t re-release particles back into the air, even when the filter is heavily loaded.

The naturally antibacterial polypropylene fibers in Blueair filters prevent bacteria and mold growth, so you’ll never add harmful particles back into the air.

Blueair less dense filter design mean lower air pressure, requiring less energy consumption. Blueair filters are also 100% recyclable, so the only thing you’re adding back into the environment is clean air.

Due to the use of both electrostatic and mechanical filtration, Blueair filters are able to benefit from lower density filter media. Less density allows lower air pressure, so you get high performance with a whisper silent delivery.

Airborne particles pass through an ion chamber to get electrically charged before passing through the gradient structure of Blueair filters. The charge causes the polluted particles to effortlessly adhere to the filter media, capturing even fine particles such as tobacco smoke.
