• Make metal vent-pipe runs to the outdoors as short as possible, with limited bends for the best airflow (45 feet max, assuming two 90-degree bends). • Install a self-closing exhaust vent, rather than a louvered one, to keep outdoor air from coming into your home when the dryer is off.• Consider putting in a bathroom-type vent fan in the ceiling to prevent moisture buildup in a laundry with a stall shower or pet-care station.
