This paper describes the actual contaminant removal performance of room air cleaners using with the latest test methods of IEC 63086 or the revised JEM1467. As results by our tests, the following findings have been obtained. 1）The CADR for particulate matter including allergenic particles such as pollen, mites, pets are larger than that for gaseous one. 2）For particulate collection including ultrafine particle and fungi, their CADR are proportional to the size of the equipment air flow. 3）Gaseous substances such as toluene, acetaldehyde and formaldehyde has smaller CADR than particulate matter one. Especially acetaldehyde is a difficult substance to remove.
