I don't know the names just that there are 2 variants. One which is cheap and one which is expensive. The cheap one does not protect you but shall protect others if you've got the virus. The expensive one shall protect you but you cannot wear it for long because it's hard to breath with it. That's what was said in germany from official site a week ago or so. May be outdated now. I Think they also said that you can get infected through eyes.. So a mask MAY not be enough at all
