Grain dust PPM to a person working in a grain dust rich environment ≠ covid particles in every day air, So…. I don’t know why you feel the need to make such a bad faith a comparison of the two.
Additionally, masks of ANY type are helpful as they can assist in the virus containment of the WEARER should they be the one exposed.
Lastly, seriously… How do you not understand that there are two sides to a mask and that air travels in more than one direction through them?
Okay. I won’t, but the NIH would like a word.
