【摘要】 [目的 ]了解广州市售室内空气清新器的过滤效果。 [方法 ]根据各样机的风量选择适当的实验空间 ,分别检测 6种样机开机与未开机两种情况下的过滤效果。 [结果 ]1～ 5号样机对可吸入颗粒物及细菌有明显滤过效果 ,过滤效率分别在 6 9%～ 85 %之间及 39%～ 76 %之间 ,对 NO2 、SO2 、CO、CO2 效果不明显 (P>0 .0 5 ) ,6号样机对所检测指标均不明显 (P>0 .0 5 )。 [结论 ]广州市售室内空气清新器过滤功能单一 ,对可吸入颗粒物及细菌的过滤效果较好 ,对 NO2 、SO2 、 CO、CO2 效果不明显。更多还原

【Abstract】 [Objective]To understand the filtering effectiveness of indoor air purifying sets in Guangzhou[Methods]The filtering effectivenesses of 6 kinds of tested indoor air purifying sets were observed under the condition of selecting optimum experimental volumes for testing according to the different filtering rates of tested setsThe data of air quality obtained before and after operation were compared and assessed.[Results]No.1 to No.5 tested sets showed significant filtering effectiveness for inhalable particulates and bacteria in air with filtering effeciency of 69%~85% and 39%~76% respectively,and showed no significant filtering effectiveness for NO 2,SO 2,CO and CO 2 (P>005).No6 set showed no signiticaut filtering effectiveness for every tested index(P>005)[Conclusion]The indoor air purifying sets in Guangzhou presented simple filtering function,better filtering effectiveness for inhalable particulates and bacteria in air,not significant for NO 2,SO 2,CO and CO 2更多还原
