Genuine Blueair filters are specifically designed to enable more air flow through the filter media. When combined with electrostatic filtration this results in faster and quieter cleaning than traditional HEPA filtration.
When used as part of the Blueair HEPASilent™ filtration process, the particle filter layer helps to minimize allergy-causing airborne particles including pollen, dust, mold spores, pet dander, and infectious particles, while the carbon layer traps odors, chemicals, gases, and fine smoke particles.
