I am ok with masks but I would like to know if there are guidelines on what kinds of masks are acceptable? It is possible to buy very flimsy "masks" that technically cover the mouth and nose but in reality are about as effective as a piece of lace. People will argue that they are masked even if the mask doesn't do anything. Will those be allowed or banned (because you know someone is gong to try that)?

​

How about masks for those who have a beard? This one actually applies to me. I have a full beard and I usually wear the masks that are made specifically to be worn with beards. Look up masks for beards on Amazon for an idea. Will those be ok?

​

Thanks.
