This is what professionals wear to work with dangerous viruses.Are you saying that my cotton bandana or polyester gaiter isn't good enough? They said anything was good enough.
I am under no belief that anything other than a 100% positive pressure self-contained breathing apparatus is doing much for you. If you think some piece of cloth protects you from any virus, wear it. I don't care. Just leave me alone and let me be.
But sure, that thing your grandma knitted will be fine too...
