Various air cleaners are available on the market to improve indoor air quality. In some cases, it was described in the catalog that they could remove not only particulate matter but also odorants. Then, to evaluate the performance of the air cleaner and to find more effective system for improving indoor air quality, 14 air cleaners on the market in Japan were tested of their performances in removing 21 typical indoor odorants. The test was carried out in the chamber that was made of stainless steel.<BR>Some electrostatic precipitation system or filtration system fitted with effective deodorant filter could remove odorants significantly, but the others could not.<BR>Removal rate of odorant depended on the odor substance, for example, dimethyl sulfide and acetaldehyde could not be removed readily by the all air cleaners. In some cases, odorous by-product was generated from some air cleaners because the oxidizer on the filter oxidized some odorants. After the air cleaner was used in the chamber of high odorants concentration, some odorant could be desorbed into relatively clean environment.
