ABSTRACT
OBJECTIVE@#In order to find whether there is the correlation between the non-oil particle filtration efficiency(PFE) and the bacterial filtration efficiency(BFE) of medical surgical masks.@*METHODS@#Non-oil particle filtration efficiency and bacterial filtration efficiency were compared and analyzed through the test data of medical surgical masks from 2012 to 2018.@*RESULTS@#When the non-oil particle filtration efficiency of medical surgical mask is over 80%, the bacterial filtration efficiency can reach 95%.@*CONCLUSIONS@#In order to reach the requirement of 95% bacterial filtration efficiency, surgical medical mask must improve the limit of non-oil particle filtration efficiency. The results of data analysis can provide reference for emergency inspection and filter material rapid inspection, and also provide reference for the revision of YY 0469 standard.
