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.
