When looking to replace your air filter, there are typically two different sizes you need to know, the "Actual size and Nominal size".
- The actual size consists of the true dimensions of your filter when measuring Length, 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 ¾.
- To determine “Nominal Size” filters are rounded up number to label filter packages. For example, a filter with actual dimensions of "19 1/2 x 19 1/2 x 3/4" will have a nominal size of "20 x 20 x 1", and that will be the measurement to look for when buying your replacement filters.

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. See how they are made.
