Important Note: Almost all furnace filters have a slightly different “actual size” than the nominal size printed on the filter. We recommend measuring your existing filter or housing and comparing it with our “Actual Size” to ensure a correct fit. The depth of 4.38” is standard for many traditional 5” filters, but variances do exist between manufacturers, including 4 7/8” and 5 1/4” options.
