综述了过滤技术、吸附技术、静电技术、催化技术、等离子体技术等室内空气净化技术净化颗粒及有害气体效果的研究进展,并统计分析了北京市主流市场上国内外知名空气净化器应用各类净化技术的净化效果。同时,说明了各类技术在实际应用时的不足。最后展望了各类净化技术应用于室内空气净化器的发展趋势。

This paper intends to give a comprehensive review of the research advances on the effect of the indoor air purification technologies to remove the particles and harmful gas pollutants from the roomin environment,which may include such branches of technology as filtration,adsorption,electrostatics and catalysis.At the same time,we have made an investigation over the well-known air purifiers produced both at home and abroad in Beijing＇s mainstream market through a statistical analysis and test of the effects of the different purification technologies that are available for the aforementioned purposes.The results of our investigation and analysis show that actually quite a lot of air purification techniques can be made effective in removing the above said particles and volatile pollutants through filtration and absorption at an effective rate of 100%,whereas some other techniques,such as those on catalysis,the static and the plasma technique have been adopted at a removing rate between 20%and30%.What is more,it is necessary to point out the defects of the single purification technique and its limited use in purifying particles and harmful room-in gas pollutants.Thus,the said defects we have proposed and analyzed should be able to provide a scientific basis for the experts concerned to pay more attention to and to improve them to increase their characteristic functions.At the same time,what we have mentioned can also help or remind such device suppliers to make profound study and promote the purifying effects in removing the harmful gas particles in the room condition,such as PM_（2.5） and formaldehyde among the mainstream brands available in the current markets.Furthermore,it is also of great significance to help the general public,particularly for the current users of such devices to get familiar with the purification features and its specific status-quo of such air purifiers so as for them to be able to select better-quality purifiers in addition to heightening their awareness of protecting the facilities they have purchased.And,finally,it is also of great need to promote further energetic exploration trend to produce higher quality air purifiers to meet the future market satisfaction for such purifiers.
