실내 공기청정기 우형에 따른 ETS 성분 감소 효과

Effect of the Types of Room Air Cleaners on the Removal of ETS Components

This study was conducted to evaluate the ability of room air cleaners to remove gases, vapor and particles from closed room contaminated with environmental tobacco smoke(ETS). The types of room air cleaners selected were paper filter, fiber filter, carbom filter, static precipitator and anion generater. The ETS measurements covered total suspended particle(TSP), ultraviolet particulate matter(UVPM), fluorescent particulate matter(FPM), solanesol, carbon dioxide, carbon monoxide, nicotine, and 3-ethenylpyridine. Tobacco smoke was generated and mixed in a closed room in which the airflow rates were in the range of 0.00-0.03 m/s. As the room air cleaners were started, the decay rates of the ETS components were measured. After the use of room air cleaners, excluding paper filter cleaner, the solid components of ETS, such as TSP, UVPM, FPM and solanesol were removed over 90%, and the vapor phase components of ETS, such as nicotine, 3-ethenylpyridine(3-EP) were eliminated about 50% as time elapsed. But even after the use of room air cleaners, except the anion generating cleaner, the decreasing rate of carbon dioxide and carbon monoxide concentration were not much different with the control. Our results indicate that there was a different removal efficiency with the types of filter materials in air cleaners, and also there was a dominant effect on reduce of solid and vapor components of ETS. But there was no significant effect on reduce of gaseous components of ETS. It is possible to increase the air quality in a room contaminated by ETS with the conditions that an air cleaner is properly chased, operated and maintained well.
