Build a Custom Size

Simply measure the length and width of your filter with a tape measure and choose the closest size (to 1/8”) in the drop down menu. 1/8” tolerance is standard and should not cause a problem in any standard filter application.

Please note that the ‘actual’ filter size, ie the size that your tape measure shows, should be used when creating a filter with this tool, not a nominal filter size. Note that the depths of each filter are standard, as shown to the right.
