Burning of tobacco produces several toxic compounds such as carbon monoxide and arsenic which can be harmful for both active and passive smokers. Therefore, cigarette manufacturers put activated carbon filters in the form of combined media filter tip or cavity filter inside the cigarettes. Sometimes activated carbon is dispersed within cellulose acetate tow at the mouth-end of cigarettes. The purpose of activated carbon is to capture these toxic gases without affecting the flavor and aroma of the smoke. 

SpaceBlack Adsorbents has a special range of granular activated carbon derived from coconut shell charcoal which can be readily used in the cigarette filter design.
