I ordered a 14x20x4 I needed a 14x20x4 Return Air Filter not a furnace filter. I did not know the difference. I need to return these four filters

Easy to install and since we have cats, do a great job plus they still look pretty good even after three months.

So far they seem to be performing well! However the pleats should be evenly spaced and the ones that I received are uneven and tight together creating areas with less air flow!

I have used Merv filters for several years now and have been very pleased with their performance. I will continue to order them in the future.
