The filters fit into our equipment and seem To be working well.. We will see how effective they are when it is time to change them out with fresh ones. Thank you for your assistance over the phone.
The filters didn't quite as tightly even though they were supposed to be for Amana - my type of units. The problem was in overall thickness - old ones were 5 1/4" wide - the new ones were only 4 3/8" wide. Sloppy Fit - Guess I should have checked actual vs nominal.
I had a problem with the size of the recommended filter for the model of furnace. I called and they took care of me ASAP! It was great turn around for the new (right sized) filter!
