AN INVESTIGATION OF THE VOC REMOVAL RATES ON DOMESTIC AIR CLEANERS : Studies on removal characteristics of indoor gaseous contaminants on domestic air cleaners (Part 2)

Abstract

Recently, the "sickhouse" has been attracted as our urgent problem. The domestic air cleaners have been widely used as a pollution mitigation measure in Japan. The removal efficiency of domestic air cleaners on some pollutants has been reported. Though we have already reported the formaldehyde removal rates on the domestic air cleaners, the detailed reports concerned with the VOC removal aren't provided yet. So, this study was carried out to comfirm the 22 VOCs removal rates of the equipments. From our results, it turned out that the VOC removal rates of the air cleaners with a rich activated carbon filters were ranged from 14.6 to 18.3 [m^3/h] by the equipment index of ECAR (Equivalent clean air rates) and the VOC ones of the electrostatic type units were only a little less than 1.40 [m^3/h].
