A dryer vent is a duct that carries hot, moist air from a clothes dryer to the outside of a building. It helps to remove excess humidity and lint produced during the drying process, preventing potential fire hazards and improving dryer efficiency. Proper installation and maintenance of the vent are essential for safe operation. Regular cleaning of the dryer vent is important to prevent lint buildup, which can block airflow and increase the risk of fires. Homeowners should check the vent periodically and consider professional cleaning services if they notice reduced drying performance or excessive lint accumulation.
