The only state now telling people to wear them is specifically saying no N95 or surgical masks, only homemade ones, scarves or bandannas. That is the problem here in the U.S. they do not want people outside of healthcare workers buying the effective ones. That is because there simply isn't enough for the healthcare workers much less people like the police. I saw an article that said that 1000 of the people in the NYPD are testing positive. There are doctors and nurses working with COVID19 patients who are wearing the same N95 mask for days at a time, some are slathering them with hand sanitizer to try to get some kind of protection. That is why I have an issue with this becoming a thing. It will be the same situation as the toilet paper, let the price gouging and the hoarding begin.Because we only get 2 a week, we wear them multiple days in a row
