These look ok but the thickness was too thin being 3.5 inches instead of 4 so I asked if they had 5 inch thickness which would've been 4.5 inches and fit my furnace much better, they indicated they didn't make them that size which was disappointing seeing they made the 5 inch thickness in other sizes but not 25x25. So I'm stuck with a couple that are about an inch too thin.

Not impressed

I would not recommend nor would I buy these again. I had issues with one which they handled since it came massively damaged. The issue is the others are not made well. You are honestly getting what you pay for here. Spend a bit more and get the good ones

Filter fitment

Works great but when a 20X20X4 filter is not 20X20X4 then I had to shim the filter to fit properly in my furnace.Other than that it is a great filter.

These filter are a waste
on December 17, 2023

These filter are a waste of time and money! These filters are undersized- not 20"x20"x4" which is printed on the side of the filter! They are 19 3/8"x19 3/8"x 3 5/8" Which means they do not seal! Air leaks around them, which means they only filter a small fraction of the air going through the air handler.
