Designed for whisper-quiet operation, this easy-to-install filter ensures your Blueair purifier delivers superior air quality without noise disruption. ## Description From the manufacturer HEPASilent-Technology Blueair’s HEPASilent filtration process captures 99.97% of airborne particles down to 0.1 micron in size. HEPASilent technology unites the best in electrostatic and mechanical filtration. Its revolutionary combination of advanced filter media and an encapsulated ion particle charging chamber ensures that your Blueair purifier delivers results far superior than either mechanical or electrostatic technology alone. Traps Particles for Good The 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! Naturally Antibacterial The naturally antibacterial polypropylene fibers in Blueair filters prevent bacteria and mold growth, so our filters never put bacteria and mold back into the air. Whisper Silent Due to the use of both electrostatic and mechanical filtration, the filter media in Blueair filters is less dense than comparable media. Lower density enables air to move through the filter at a lower pressure, so you get high performance with a whisper-silent delivery of clean air. Review: Works well. - Easy to load.
