Dehumidifiers reduce the moisture in the air. They provide comfort for people and reduce or eliminate deterioration of equipment due to rust, rot, mold, and mildew. The most commonly used dehumidifiers consist of a refrigeration unit with an exposed cold coil, which condenses moisture from air as it is drawn over the coil by a fan. As moisture condenses it drips in a pan or flows to a drain. If a drip pan is used it must be emptied regularly. Home dehumidifiers will remove from five to 15 quarts of water from the air daily.
