In my shop the installer transitioned from a 20x30 to a smaller maybe 20x20 duct very quickly with sheet metal so the back of these hit the duct.
Luckily it is a shop and the looks don't matter so I throw a "normal" 2" 20x30 filter where a 1" goes and just take off the pretty cover. :-)
I can't find "normal" 4" 20x30 anywhere though. Booo!
So I added a second return in the ductwork running up 12' to the unit at the ceiling. Now I can let both filters get extra dirty before changing them since there is airflow through two of them.

and now suddenly its not.
I've been using MERV 11 for 25+ years on the same AC. Curious what the experts say.
