摘　　要：阐述了目前我国主要的四种针对空气净化器甲醛净化能力的测试方法,分别为洁净空气量法、洁净空气量法(修订)、净化效率法(适用面积下,1 h)和净化效率法(30 m3测试舱内,1 h),同时选取7款市场在售不同品牌空气净化器进行测试验证,并就方法的适用性展开探讨。数据表明,按现行洁净空气量法测试,7款空气净化器中4款无法满足规定的可靠性要求;按修订后洁净空气量法测试,仍有一款无法满足放宽调整后的可靠性要求;按两种净化效率法测试,所得结果无明显对应关系,适用面积下运行1 h净化效率法相对适合评价空气净化器净化甲醛的实际能力。In this work, four formaldehyde testing methods using in China, which are CADR method, CADR method（revised draft）, Purification method（related with applicable room area, run time 1 h） and Purification method （run in 30 m^3 test chamber, run time l h） , were reviewed and compared, to test the removal capacity of formaldehyde by 7 selected air cleaners with different brands on sale in market. It was found that 4 of 7 selected air cleaners can not meet the reliability requirements on clear air delivery rate （CADR） using the current national CADR method. If the modified CADR method was applied, only I of 7 selected air cleaners can not meet the reliability requirements. According to the tests of two Purification methods, the results are not comparable, since both of these data are in different range. It seems that the Purification method （related with applicable room area, run time 1 h） is more suitable, to evaluate the removal formaldehyde ability of the air cleaners.
