The Gas & Odor (GO) SMOKESTOP Filter is the best choice for allergy sufferers and other health-conscious individuals that need all the benefits of the particle filter above, PLUS the removal of gases, odors, smoke, VOC, and other chemical vapors. The SMOKESTOP filter is a progressive activated carbon filter with a honeycomb-type structure that is composed of thousands of tiny odor and gas absorbing carbon pellets. The activated carbon is impregnated with a 70/30 blend of Potassium Hydroxide (KOH) and Potassium Iodide (KI) for bonding/trapping chemicals / VOC's in the air, which contribute to odors.
