My comment was explicitly pointing out that closing the lid can have the opposite of the intuitive effect and make things worse even though you’d expect it to make them better. It seems that I misrepresented the study’s findings, though, as while closing the lid does make particles remain airborne for much longer, so my overall point is sound, closing the lid does reduce the number of particles that initially become airborne.
I think I did not understand your comment. Isn’t it the other way around?
No it’s not.
