I have no experience using a PAP of any flavor COVID or not, but if they just need face covered or a full face mask, it's a toss up. You get to decide, but maybe some face covering is the one easier to do. Early on in the COVID mask requirement, I just got a 3 pack of bandanas at the dollar store and folded one into a triangle and tied it in a knot to hold it over my face. It is a face covering. Then again there is this plexiglass face shield that I have that is also a face covering. So really take your pick and go with it.
Bet this is the only time in history we see lots of people roaming around at an airport and they aren't getting arrested.
