I was... year-after-year (1994 to retirement... required to maintain OSHA 1910.120 certification "Hazardous Waste Operator" at the Supervisor level. 10 CFR 1910.120 App B is the part of the federal regulation which deals with PPE (personal protection equipment). Of special intent is to protect the wearer from substances based on "particle size." https://www.osha.gov/laws-regs/regulations/standardnumber/1910/1910.120AppB
The particle size of viruses ranges from .0016 to .01 microns. In comparison, tobacco smoke is .013 to .19 microns. Both of these fall in the "ultrafiltration" range.

To test our PPE masks, we were required to have a clear shaven face and the mask fitted and adjusted so that we could not smell smoke (if ultrafiltration).
So... if you are concerned about corona virus put on your mask and have someone smoke a cigarette near you. The question is: Can you smell the cigarette?
HOWEVER... I do not have a problem with folks who wish to wear a mask because it makes them more comfortable or lowers their anxiety level. I cannot protect them from viruses without purchasing and wearing a qualified ultrafiltration mask... and they can't either.
I am more concerned that folks who are ill with the virus stay away from me... "Maintain Social Distancing"... and maintain personal hygiene (wash their hands). The COVID 19 virus is VERY fragile outside the human body.
I refuse to be stampeded by the media, politicians, and various "experts." Their messages are stressful, conflicted, confusing, inconsistent, and amorphous. Remember this after the election in November. Because the whole "virus message and behaviors" will change IMMEDIATELY after the election.
