I'd like someone, ever, just one time, on the entire internet, make a real case for not using the screen on a vent like we have.
There's a lot of
'I would not do this ever', but no substance presented ever.
I use the large cut stainless steel wool like used as kitchen sink scrubbers. Stuff it in a hole. Now there is no more hole and less than 2%+- added restriction.
It cuts or expands well, becoming a pad/plug of whatever size needed.
