400 Series Particle Filter

Product Description

Superior HEPASilent^® technology.

Blueair purifiers combine electrostatic and mechanical filtration, allowing filtration to perform at peak performance levels for longer periods of time. The two types of filtration expertly work together to trap particles from big to small.

Traps particles for good.

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.

Naturally Antibacterial.

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

Environmentally Friendly.

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

Anti-shedding and chemical free.

Our fiber media is free of chemicals and binders and ultrasonically bonded to prevent new particles from being added to your environment.

Whisper silent.

Due to the use of both electrostatic and mechanical filtration, our 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.

Electrostatic cling.

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