DEEP PLEAT FILTER SIZES
The sizes below are plus or minus 1/8". The Nominal size is but just a name. This is why you will see, for instance. three 20x25x5 and all three will have different "Actual" sizes. This is because 20x25x5 is just the name of the filter and the actual size depends on the manufacturer.
Many manufacturers use the same sizes so when you click
"Go TO IT" you may land on a page that has your size but a different brand than what you have. This is OK because these are aftermarket filters and the only thing that matters is the actual size of the filter.
