Abstract: Some domestic ionization-type air cleaners incorporate or solely rely on corona effect to electrically charge particulates so that surface deposition velocities of dusts are accelerated in indoor environment. On the other hand, ozone, as an indoor air pollutant, is generated as a by-product. Two standard test procedures exist, respectively quantifying the dust removal capacity and ozone emission. However, these standards fail to adequately specify the chamber surface decay effect with regard to ozone and particulates, which will add uncertainty to the test results. In this paper, we will present our testing results on 27 commercially available products in Hong Kong to illustrate the significance of chamber surface deposition effects. The results will be useful for the manufacturers to quantify the performances of their product design.
