You can maintain a consistent look, with the Dryer Wall Vent's low profile aesthetics, for bath vent fan exhaust terminations. The only requirement is that the fan pushes air at 70 Cubic Feet per Minute (CFM) or higher (most quality fans exceed that). When deciding on a bath fan, it is good practice to select a higher CFM. The idea is that the faster air is replaced in your bathroom, the more quickly humidity is removed.
Why a minimum CFM? The balanced, low-power magnets that help prevent pest intrusion and negative pressure flapping, require a little boost to open.
