All of our pocket filters are stated in nominal dimensions, not exact dimensions, which is common industry practice. Pocket filters are placed into a holding frame, usually via a metal track. To allow for easy insertion and removal, pocket filters are typically constructed 0.5” inches smaller than their holding frame. For example, a pocket filter with an actual width and height of 19.5” x 19.5” is referred to as 20” x 20” filter because the holding frame into which the filter is inserted measures 20” x 20”. Or put another way, add between approximately 1/2” to 11/16” to the actual measurement of your pocket filter to determine its nominal dimension.
