lol masks aren't perfect. like i said they're not magic. but they do have a purpose when it comes to respiratory virus, to say otherwise is nonsense and 42CRF doesn't mention PPE.
The 42 CFR is the US regulatory guide for mask selection for chemical and biological contaminants based on many environmental factors.
Hey and by the way, if you are able to actually read and understand the 42 CFR and figure out the applicable part and subpart SPECIFIC to respiratory protection (I did not give you that on purpose because if you knew ANYTHING about respiratory protection as it applies to biological you would have had no problem here), why don't you advise on the respiratory protection recommendation for Tuberculosis and how it differs from COVID and of it does...why. Be specific.
LOL.
Keep wearing that dirty rag on your face day in and day out and get your vaxx.
