This research determines chemical substance removal rates of domestic air cleaners using with thepollutant constant-emission test. In previous studies, we have already reported the formaldehyderemoval rates of room air cleaners and the high accuracy of our method for predicting indoor pollutantconcentration. In the present study, the VOCs removal rates of room air cleaners were measured.Gas-phase contaminants were supplied to the environmental test-chamber using a custom-builtemission device. And performance evaluation test was conducted to two kinds of air cleaners.
