Ordered 20x25x4 for aprilair system and the size of filter is off by 2inches. It would be better if filter buy has a exact measurements

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.

I need to return them. They do not fit, even though the measurement seemed to be correct.

Great product at great price

Unbelievable how some companies charge way too much for a lesser quality product. I purchased the Merv 13 pleated filter, 16x25x4 and couldnt be happier. The price was equivalent to what others wanted for a basic low quality filter. They were shipped in a timely manner and I received them in just 3 days. Fit is perfect and time will tell on the performance.
