Description
xOverview
The BLUEAIR Classic 400 DualProtection Filter combines an activated coconut carbon layer with a high-porosity particle filter to address odors and airborne particles. Built to work with HEPASilent technology, it aims to preserve clean air delivery while targeting gaseous pollutants such as smoke, VOCs, and everyday odors. The coconut carbon is powdered for quick, even treatment inside the filter, and the pleated design enlarges the filter area for more contact with incoming air.
In daily use, you may notice faster odor and pollutant capture, along with thorough filtration for common indoor irritants like pollen, dust, pet dander, and mold spores. The filter is designed to fit a range of Blueair Classic models, and the recommended replacement interval is roughly every six months to sustain performance in typical environments.
