Insane AC drain story....

Here's a photo my units with the AprilAire filter boxes installed under them:

Interesting...the only filter that I've changed is the one inside the house. I never thought to look at the furnace to see if one is on the unit.

Psypher- that was a photo I found online - the unit in my attic a lot more cramped in there if you could picture that as possible. my place is a split ranch home .my neighbor has half the building and the wife and I the other 1/2. my unit kind of L shape design and runs behind the attached 2 1/2 car garage.

It just depends where the installer put it. Usually the filter (here in Florida anyway) is right at the intake of the air handler. However, I have seen some installations where the filter is in the intake vent inside the house.

If anything, it would act like a P trap and keep bugs out. Might get a frog trying to live in it LOL.
