The actual dimensions of the 16 X 25 X 4 are advertised as 15.88 in x 24.56 in x 4.31 in. However, the actual depth of the filter is only 15.44 (15 7/16) in as seen printed on the filter. This leaves a gap on top of the filter that the air can circumvent rendering the filter fairly worthless.

Run slightly bigger… doesn’t fit. I had to purchase brand. My disappointment is that I’m reading olds comments and reviews (about 2 years ago) and looks like the brand is not interested to fix this issue.

Too restrictive does not allow enough air flow. My 5 ton unit is sized correctly for my home. My return is 1024 sq in Unit struggled to cool with these in higher temperatures. Unit is less then a year old as soon as we put a less restrictive filter in the air flow was better and unit was quieter.

I went to check the filter for replacement and there were no tabs to easily grab it. The thin carbboard also got stuck when trying to get it out, totally destroying the filter.
