Anyone not wearing a mask has my personal blessing. I think each person has a right to make that decision.
Just as businesses have that right to deny entry to folks without one. No different than 'no shoes, no shirt, no service', both of which are fully legal. Can be debated if a governor mandates it in public places. To each their own on making such decisions. Hopefully either side of the coin will respect folks that are compromised or the elderly. I said all along I think we as Americans have rights first and foremost.
I don't mind if someone chooses not to wear a mask as I know they are exercising their rights. But if I choose to wear on for a few minutes while grocery shopping, than that too should be respected.
And if I'm reading that article correctly, they are wrong. If a mask filters down to the .03 micron level, then things larger, such as .06-.14 cannot get through.
Ok, I think I am reading it wrong, but not so wrong. Yes, n95 will work, and n99 will work even better. But the mandates of wearing A mask is about preventing the majority of droplets from exiting should someone cough or sneeze. Perfection? Far from it. But anything blocked helps. And the fact that regular ones are far from perfect, and the n95/99 work, is why those are the models I have.
I do have others to wear because of the mandate, but a medical mask as such is far from always needed.
Also, the n95/99/ffp2/ffp3 and onward, aren't masks that "our" USA medical field are wearing, so nothing much being taken from them. Even the 99's I just got are MUCH higher rated than our n95, but it's a Canadian mask and not certified here in the US by the CDC.
