Get the vax, please, everybody. It could make the difference between not getting sick at all, not getting hospitalized if you do get sick, and not spreading it to people more vulnerable than yourself.Granted they are different standards, the KN95 standard is still tested against 1 micron and 95% filtration similar to an N95. They actually work extremely well against bacteria if you get a legitimate one. There are fakes of KN95s running around right now.
And wear a mask to provide that extra layer of protection. N95 and KN95 help protect both you and other people; surgical masks, somewhat less; bandannas etc are a joke. A mask with a valve in it lets you breathe bad stuff on other people--not good. A face shield is useless. You can get N95s now and it is literally the LEAST you can do for your fellow humans--not to mention for your own good.
I guess all the masks are wireless. Here's a list of sources for real ones.
