Set up your dehumidifier in the most humid room. The rooms that usually hold the most moisture are bathrooms, laundry rooms, and basements. These are the most typical places to install a dehumidifier. Dehumidifiers can also be used on a boat while the boat is moored to a dock.
To maintain the correct humidity level in a basement, place a dehumidifier in the basement, and connect it to the existing main stack, feeder drain or utility sink. If the dehumidifier doesn't measure the level of humidity automatically, place a hygrometer next to it. You can also turn on the exhaust fan when somebody is showering or venting the clothes. The ideal moisture level for a basement ranges from 30 to 50 percent relative humidity.
