Does this work for surgical masks as well? Are they actually comparable in filtration size to N95? I need to look up all the values... Edit: from cdc guideline

Does this work for surgical masks as well? Are they actually comparable in filtration size to N95? I need to look up all the values... Edit: from cdc guidelines: >SARS appears to be transmitted mainly through direct contact with infectious materials (including large respiratory particles), and surgical masks will provide barrier protection against droplets that are considered to be the primary route of SARS transmission. However, surgical masks may not adequately protect against aerosol or airborne particles, Presumably as coronaviruses SARS and COVID19 are similarly sized, and I don't know that the aerosolization of COVID19 has been confirmed. So at least in a casual setting like stores I imagine masks should reduce the probability of inhaling viral particles.
