The true measured dimensions of a 16 x 25 x 5 in filter and how to order it.
The nominal size 16 x 25 x 5 in is the name on the frame; the actual size is 15.75 x 24.75 x 4.375 in. On a flat filter each face runs about half an inch under nominal and a one-inch filter is really three quarters of an inch thick.
The narrower five-inch media filter, actual 15.75 by 24.75 by 4.375 inches. Like the 20 by 25 by 5 it is only about four and three-eighths inches deep despite the five-inch label.
