The Blueair SmokeStop Filter is a progressive carbon filter with a honeycomb-type structure that improves airflow and has hundreds of odor and gas absorbing carbon pellets. The filter contains 2.0 lbs of coconut shell activated carbon impregnated with a 70/30 blend of Potassium Hydroxide (KOH) and Potassium Iodide (KI). The carbon eliminates volatile organic compounds (VOC), which are responsible for odors and often found in household paints and cleaning products. The Blueair GO SmokeStop Filter is recommended for use in rooms where heavy gaseous pollutants such as cigarette and cigar smoke or other VOC's are present.
