I know most on this blog are mask averse. But, after studying research and finding they are useless, I also found there are degrees of useless, it's not black and white. It depends on time, air filtration, viral load, immune system, type of material in mask, fit, particle size, etc. Most particles don't go past the throat and nose, but one would have to disinfect the throat and nose, and eyes, N95 masks can't be washed, so I don't know how handing out a few masks can help the public.

I wonder how the Cambridge mask (.com) fits in with your analysis? No one mentions this one but it is an N99 and is washable and independently tested. It needs to fit well, which it usually does. It's not 100% protection, but better than other masks, especially since it has a vent (or no vent option). Of course, that won't protect others, but it does protect the wearer. If one covers the vent with a surgical mask to protect others, it's still easier to breathe than with no vent. If one wants protection for themselves, it works better than others. In wildfire smoke, I can't smell a thing; but it works for viruses, too. See their certificate of analysis. BTW, in doctors office, they usually sort for symptoms. So, the level of spread is lower if asymptomatic. Inside other public places, who knows?
