The Blueair 400 Series Particle Filter is a replacement particle air filter that traps dirt, dust, pet dander, bacteria, mold spores, dust mites, and other airborne allergens. It also removes odors and gases from the air. These Blueair 400 Series Particle Filters feature HEPASilent filter technology which removes 99.97% of particles to 0.1 micron.

This replacement air particle filter is a compatible replacement for Blueair 400 Series models including the Blueair 402, Blueair 450E, and so on. It is compatible with all Blueair 400 Series Air Purifiers. The dimensions of this air filter are 22 1/2" x 11" x 4 1/4" - please check the size compatibility with your old filter before purchasing this one.

This Blueair particle filter is made of polypropylene. To maximize filter effectiveness, particles are negatively charged before reaching the particle filter. The Blueair filter system is a 3-stage progressive filter that uses ion technology and produces zero ozone emissions.

Blueair recommends replacing these particle air filters every 6 months. Replacing these air filters is easy: just open the lid of your Blueair filtration unit, lift out the old filter, and then drop in the new replacement air filter. This Blueair particle filter resists clogging so that filtration always occurs at the highest possible levels. It is also water-resistant.

This is a genuine Blueair replacement particle filter.
