"sick house" is a serious air quality problem which should be immediately solved. On the other hand, domestic air cleaners are widely used as prevention technology for indoor air pollution. Air cleaners are usually classified by the method employed to remove particles of various sizes from the air. There are three typical types of air cleaners on the market. They are mechanical filters, electronic air cleaners and ion generators. Some air cleaners are designed to remove gaseous pollutants as well as particles. However, studies on the removal effectiveness of portable or domestic air cleaners on gaseous pollutants are limited. So we conducted an experiment study with a testing method in the constant-pollutant emission to the air cleaner. The performance was expressed by the index of equivalent clean air rate or ECAR[m^3/h]. Tbree types ofair cleaners' ECARranged from 16.1 to 17.3[m^3/h]. In this report, our prediction method on indoor concentration was confirmed and result showed that the correspondence rate between measured value and predicted one of formaldehyde concentrations were 76.5 to 99.9[%].
