Dryers vented refers to clothes dryers that expel moist air and heat from the drying process to the outdoors via a venting duct. In a typical setup, warm air is drawn through the dryer's drum, heated, and circulated to dry fabrics. The humid air leaves the drum and passes through a lint filter, then through a duct to an exterior vent. This design contrasts with ventless or condenser dryers, which remove moisture internally or condense it from the air.

Vent systems are usually 4-inch diameter metal ducts with a backdraft damper on the exterior cap. Ducts should be as straight and short as possible, with minimal bends to reduce heat loss and lint buildup. Materials should be rigid or semi-rigid metal; flexible plastic or foil ducts are generally discouraged as they collect lint and are fire hazards. Exterior vent caps should remain clear of obstructions and be sealed against pests and weather.

Safety and maintenance: lint buildup is a major fire risk, so the lint filter should be cleaned after each load, and the vent and duct inspected and cleaned periodically. Ensure the vent exits to the outdoors and that there are no kinks or crushed sections. For gas dryers, proper venting is critical to prevent carbon monoxide buildup.

Regulations and efficiency: many building codes require exterior venting; improper venting can reduce efficiency and cause moisture problems in the home.
