Query: filters are too small!

These filters are marked 20" x 30", but in reality they are 19 5/8" x 29 1/2". The flange around the edges of my filter enclosure is too narrow, these just fall through. I cannot understand how someone can get away with labeling something incorrectly like this. I wonder if all of there sizes are mislabeled?
