Indoor air pollution problems in dwellings can stem from a widely and variety of sources, such as building materials, furniture, paints, combustion heaters and etc. In recent years, there has been an increased interest in devices that are generically called air cleaners.Recent concern has mounted to supply purified air for occupants. Several studies on removal of SPM by air cleaners have been conducted, however, in these reports, we can not find useful information which is related to quantitative removal performance of gaseous phase contaminants. So, this study was carried out to determine the removal effectiveness of the appliance on formaldehyde by an environmental chamber, and the evaluation used with the index of equivalent clean air rates(ECAR). From our results, it turned out that removal rates of formaldehyde were 8.10〜19.9 m^3/h by the ECAR on domestic air cleaners with activated carbons or chemical sorbents filters. The ECAR is equaled to ventilation rates of rooms.
