20x23x1 air filter amazon?

Installation is simplified by the inclusion of easy-to-understand arrows in the frame that help identify the direction of the airflow and, subsequently, the way the filter should be positioned. If your current air filter doesn't have a dimension indicated on the frame, take a measuring tape and record the length x width x depth to find the actual size.
