The best I've seen on this, can't find it now, is something like:
A good n95 mask will knock out maybe 98% of the likelihood of getting a virus (and remember, if you're distancing, the likelihood of encountering a virus goes way down in the first place!)
A multiple layer bandana maybe knocks the likelihood down 80%? 60%? So not as good as an N95, but much much more than nothing.
There's stuff out there comparing n95 to surgical mask, and maybe to a bandanan, but i don't have time to find --have to work this weekend.
