For those who live in humid areas, the battle against mold and mildew is a constant struggle. The Dampp-Chaser Closet Dehumidifier Rod is a very simple electrical device that is mounted on the closet baseboard (brackets are included). The dehumidifier rod warms, dries and circulates air in the confined storage space through a continuous convection process. As the air is warmed, it becomes lighter and rises to the upper section of the enclosed space. At the same time, cooler, moist air sinks to the bottom where it is warmed again and the cycle begins again to keep your stored valuables protected from mold, mildew, rust and rot. The slight warming and drying of the air lowers its relative humidity and combined with the gentle circulation of the drier air; results in just the conditions you need to discourage mold growth. Just be sure to leave the Dampp-Chaser on during the moist seasons. Electrical use is minimal. For pennies a day, you can be assured of mold-free clothing and easier breathing.
