Certainly truth to that. I have to explain different N95 masks weekly so I get your point.
We did this 20+ years ago and we were just trying to get rid of the haze of the bar and keep the walls and surfaces cleaner. IAQ wasn’t really a thing anybody talked about. Throwing some smoke rated air filters on the sides of an empty cardboard and pulling air through them seemed like an obvious and easy fix and it did make a significant improvement immediately. No peer-reviewed testing in the dive bar scenes so no real information to provide.
