The Key Pleat Air Filter is a standard capacity pleated filter, available in 1", 2" or 4" depths and several standard face sizes to accommodate most system requirements.

The inside of the die cut frame is coated with adhesive to ensure a solid bond at all points of contact with the media pack. The pack is sealed inside the frame and pleat tips are bonded to the stabilizers and diagonal support members. ** Facts about home and business air filters, Allergies, and filter quality: When looking to replace your air filter, there are typically two different sizes you need to understand, "Actual Size and Nominal Size". First: The Actual Size consists of the true dimensions of your filter when measuring height, width, and Depth (thickness). These dimensions typically include a fraction of an inch within them. For example: 19 1/2 x 19 1/2 x 3/4 Second: What you might not realize is that filters are not sold by their actual dimensions. Instead, a rounded up number is used to label filter packages. This measurement is referred to as the "Nominal Size". So a filter with actual dimensions of 19-1/2”H x 19-1/2”W x 3/4"D will have a nominal size of 20”H x 20”W x 1"D, and that will be the measurement to look for when buying your replacement filters
