Dehumidifiers need clearance for air to flow in and out of the unit. They also need to be plugged into an electrical outlet. In a large room, place the unit near the source of moisture. In a smaller room, a central placement is ideal.
Where should dehumidifier be placed?
Where should I place my dehumidifier? The best place for a dehumidifier is the room you need it in most. Dehumidifiers are commonly placed in bedrooms, basements, laundry rooms, crawl spaces, and indoor pool areas since these areas often have moisture problems.
Does a dehumidifier have to be centrally located?
When placing a dehumidifier in a crawl space, it is important to ensure that it is centrally located with adequate clearance. Depending on the size of your crawl space, it may be helpful to use a fan to circulate air around the crawl space. Circulating the air in tight spaces will aid in dehumidification.
What number should I set dehumidifier at?
The optimal relative humidity level is between 30 and 50 percent, according to Energy Star (and 30 to 40 percent in colder areas during heating season). If the humidity is higher than that, it can breed dust mites, mildew, and mold, and trigger allergies.
