The effect of dust source, dust concentration and wind (1.China Academy of Building Re- search, Beijing 100013; 2.Beijing speed on particulate purifying efficiency of electrostatic air cleaner was studied respectively University of Chemical Technology, in the case of KCl aerosol and loess dust as detecting dust source. The result showed that Beijing 100029) the purifying efficiency was more higher in the case of loess dust as detecting dust source than that KCl aerosol as dust source, the purifying efficiency of PM10 and particulate with particle size more than 0.3 μm were very clos
