Eh, I’d argue with IAQ that I don’t want to go with mere common sense. I want to see it demonstrated to work. Which people have done now regarding covid aerosols and other particulates, which can be difficult to capture. These devices have been shown to work to catch them, while other DIY solutions don’t always. Similar to masks. N95s have a lot of engineering behind them. Sometimes things really are more complicated than they appear
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.
