Acetaldehyde accounts for most of the gaseous substances in cigarette smoke. “In cooperation with KT&G, KIST has developed a nano-catalyst filter coated with a manganese oxide-based nano-catalyst, which can be used in a smoking room to reduce and purify major harmful substances of cigarette smoke. The KIST-developed catalyst removes 100% of the particle substances of cigarette smoke, such as nicotine and tar, converting those into water vapor and carbon dioxide. According to the research team, the air cleaning equipment based on the newly-developed catalyst can purify over 80% of the cigarette smoke within 30 minutes and 100% of it within 1 hour in a 30 square meter smoking room, where 10 people are simultaneously smoking” said Dr...
