About the 16x20x2 air filter
The 16x20x2 air filter is used in 2" filter racks in light commercial and residential systems. As with all air filters, the size is given as length x width x depth in inches. The 16x20x2 label is the nominal size; the actual filter measures about 15.5 x 19.5 x 1.75 inches.
If your system uses 16x20x2, you can choose the efficiency that fits your needs — from basic equipment protection up to MERV 13 for allergies, pets, and wildfire smoke. For higher efficiency without an airflow penalty, consider moving to a deeper 2", 4", or 5" cabinet if your system allows.
