ã€Abstractã€‘ Two kinds of sampling methods for air microorganism-impacting method and plate sedimentation method were selected to sample the natural bacteria in the air before and after treated with the two air cleaner.The purification effect of the two devices can be evaluated with microbial decay rate,which shall be obtained by comparing the numbers of colonies of bacterial in the air before and after purification.Conclusion:The photocatalytic air purification device has a higher decay rate of airborne microorganismsand the impacting method is more reasonable to evaluate the results.æ›´å¤š è¿˜åŽŸ
