Clearing the clean code was the hardest part.

I had no problem installing the new filter. Just used a phillips screw driver to remove the two screws holding the vent cover in place. Cleaned the dust out of the ducts and reinstalled the new filter. The screws must be held to the screw driver with your finger tips so you don't drop them in the vent cover. The most difficulty I had was in clearing the clean code from the screen. There are no instructions in the owners manual for doing this. But after several tries I got it.
