ObjectiveTo evaluate disinfectant efficacy of air disinfector and  ultraviolet  lamp.MethodsDomestic literatures were searched by computer, RevMan 5.3 software provided by the Cochrane collaboration  was used for quantitative analysis,  efficacy of two kinds of air disinfection methods was compared. ResultsA total of 11 articles met the inclusion criteria. Because the heterogeneity of literatures, random effects model analysis was adopted,  colony forming unit (CFU) before disinfection（WMD=-26.28，95%CI：［-60.31，7.75］，P＞0.05 ）and immediatelyafter disinfection（WMD=22.45，95%CI:［-34.24，79.13］，P＞0.05） had no obvious difference between two methods respectively,  but CFU of air disinfector 2 hours after disinfection  was significantly less than ultraviolet lamp group（WMD=-345.11，95%CI:［-478.28，-211.94］，P＜0.05）.ConclusionAir disinfector has good continuous disinfection efficacy.
