Cigarette smoking causes serious diseases through frequent and prolonged exposure to Toxicants. Technologies are being developed to reduce smokers' exposure safeguarded, including the tobacco filter Adsorbents treatments and substitutes. This study examined the effect of modifications to filter ventilation, and active charcoal filter length and loading, as well as use of porous substances and chemical reactions, on the yields of Toxicants in cigarette smoke. Earlier, an air-dilution mechanism, called split-tipping, in which a band of porous paper was developed at the Center of the filter...
