Blueair 400 Series Replacement Particle Filter for the 400 Series Air PurifiersThe gradient structure of Blueair filters traps particles of all sizes while maintaining maximum airflow. It resists clogging and won’t re-release particles back into the air even when the filter is heavily loaded. Blueair filter media is ultrasonically bonded to prevent filter fibers and other particles from being added back into your environment. The only thing that comes out of our filters is clean air! In addition advanced polypropylene filter media removes particle pollutants down to 0.1 micron in size from your indoor air such as pollen dust and pet dander. The Blueair Classic Replacement filter Particle keeps cleaning the air on average from 6 months to a year. RECOMMENDED to change filter once every 6 months or dependent on usage. This filter can be recycled after it’s changed. ENERGY SAVING Blueair air filters save energy due to a low-density design and requiring less pressure to push air through the filters. The filters are also 100% recyclable so the only thing you’re adding back into the environment is clean air.
