Please see the pics.

One side is like new, the other side has a dent and the screen is pressed into the middle.

I'm thinking if you install the good side facing the return air it will work just fine.

Or if you want to reshape the screen with some needle nose pliers if you're handy that might work as well.

There are no holes, it's just deformed in the top middle on one side as shown.

Sold as is as shown.
