Blueair Air Purifier Classic Filter 400 SM, White

Product Summary

• HEPASilent™ filtration process captures 99.97% of airborne particles down to 0.1 micron in size
• Airborne particles pass through a chamber of the Blueair air purifier to get electrically charged before passing through the gradient structure of our filters
• 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
• 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
• Blueair SmokeStop™ filters have a highly porous structure made of activated carbon to trap gases and odors
