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.
Shopping for a dehumidifier: 1  Recommended indoor winter humidity levels are 30-40 percent. 2  To determine the humidity in your home, buy a hygrometer (humidity gauge) for $15-$80 (mechanical models are the least expensive; electronic versions cost more) and take readings in different rooms at different times. Dehumidifier capacity is generally measured by how many pints of water a unit removes from the air in 24 hours. 2  A mini-dehumidifier (1-10 pints) for a bathroom, closet or under a counter usually costs $40-$70.
