Do Masks Claimed Anti-bacteria Have More Effect

Not really. There are two main factors in determining the respiratory effect of masks on preventing pathogenic microorganisms in the air, one is the filtering efficiency of particulate matter, and the other is the close fit of the mask to the face. Although some mask materials are claimed to be bacteria killers (which depends on the reliability of the evaluation method), this bactericidal product cannot avoid bacteria that penetrate the mask and leak from the seal, so that it does not have a better performance in protective effect overall.
