I use 3M 8210 masks for ... mowing the lawn and generating wood dust in my garage. I bought a case of them January '20 from Jamestown Distributors, a boat chandlery in Maine. The guy asked me if I needed the blue medical ones, I said, no, the commercial ones for woodworking. He said then, that someone had just ordered ALL of the medical-grade masks they had, for shipment to a place called Wuhan, China. What I knew (from 3M) and didn't tell himwas that the commercial 8210 ones and the medical ones are identical except for the blue hydrophobic coating on the medical ones. As I didn't expect to be spattered by patient's blood or other precious bodily fluids, I figured the cheaper white ones would do. Later, the government, in all its infinite wisdom told civilians to downgrade to a piece of cloth, not to protect yourself, but to protect others!! (how beautifully altruistic!). I gave most of mine to pastors I knew because they would be more likely in contact with sick people. Anyway, I, my family and all the pastors in my church got it in October and all got over the Chinese Bad Cold. Whoopee. If someone tells me about not wearing the mask I just tell them I already had it, not getting the shots either, as I don't want to induce the cytokine avalanche, and most libtards sorta hang up there. I still have almost 2 boxes of the good ones in case I feel the need to make sawdust again.
