We have a cabin on the lake and the basement humidity level is very high causing mold and mildew to form. We don’t have a drain so needed a unit with a pump to pump the water into the bathtub. We also needed something that wouldn’t need a lot of attention as we are not at the cabin a lot. This unit has fit the bill perfectly. Not only was it easy to install but brought the humidity level down immediately and shuts down when the desired humidity level is reached. We ate very pleased with the unit.
