Blueair 400 series replacement SmokeStop air filter

Fits the 400 series model.

Replacement period

For continuous use it is recommended to replace the air filters every 6 months.

HEPASilent technology

This replacement air filter has a certified efficiency of 99.97% for particles down to 0.1 micron such as dust, pollen, bacteria, pet dander and mould spores.


SmokeStop™ technology

SmokeStop™ technology involves enhanced activated carbon to dramatically reduce gaseous pollutants such as exhaust fumes, cigarette and cigar smoke, carbon monoxide, ethylene oxide, ozone and other VOCs (volatile organic compounds, including household paints and other chemicals). Adding activated carbon to a filter may affect airflow and CADR between 5 -10%. You may also notice a slight odor from the carbon when the filter is first used; this will quickly dissipate.
