  1.  @jayh9635  Though I've searched. I've found absolutely no scientific evidence to the fact if masks do or don't work. Every brand of mask and make will provide different levels of potential protection. But unless you have two or more controlled groups (hundreds in each group) in a controlled similar environment, I don't see how it's possible for either side to determine if masks are truly effective or not.
