Probably actual p100 masks do stop COVID. This is because the filtering is far stricter, blocking all but a fraction of a percent of particulates. With such a mask you lose all sense of smell, an indication thst it is filtering everything.
I used one pre vaccine and didn’t ever contract it, but that is just an anecdote.
