Probably ordered the wrong thickness. Too thick to fit into my housing's guides. All the 5" thick filters are 4.XXX" thickness. These are a little more 4.XXX" than I need.

My HVAC guy recommended these exact filters. The company he worked for offered a lesser quality filter for a comparable price which is a bummer. The difference between filters is the fit of this one based on the foam edge. The other filter fit but he said would wobble in place. Lesson learned. I am thankful I have a service technician who cares about his customers.
