**** Important note about filter sizes ****
Filter manufacturers label there filters by the nominal size (the size of the return air grill opening) wherein the actual size of all filters are smaller than labeled. Filters are smaller in order to be inserted into and removed from the return air grill opening with ease. For example, a 20" x 20" x 1" filter ( the nominal size labeled by the manufacturer) actually measures 19 1/2" x 19 1/2" x 3/4". This is true of all filters. So if you want a filter with a tighter fit, measure the grill and say that you want the exact size.
You can follow the steps below and/or look for a size on the existing filter you have.
1. Open up your filter grill and remove the filter.
2. Measure the width and the height of the grill opening to determine your filter size.
Be sure that the tape measure is in front of the lip that holds the filter from being sucked into the return air.
Enter the measurements in the form above.
