If I hear one more f-ing moron say “well it’s better than nothing,” I’m going to flip out. No. It IS nothing.
Post the peer reviewed conclusive medical science, that was established years before any COVID, that has determined that even a medical N95 mask can stop any virus.
Masks are designed for much, much larger bacteria. Often 100’s of times larger and CAN get inhibited by the mask fiber mesh geometry.
Actually, it is much worse than nothing. Trapping bacteria around your face, and constantly rebreathing it is a good way to end up with bronchial pneumonia, among other things.
