Unless you wear a FITTED N95 mask with a vent they DO NOT work.
My wife just picked up a couple black mesh masks. They are perfect for all the “mask police Karens” in your travels.
From 6’ away(proper social distance) they appear to be solid black material. Up close they have a mesh fabric with holes about 3mm across. This allows you to breath easily and not fog up your glasses.
I am not sure where she purchased them.
