Dehumidifiers remove moisture from the air to dry indoor spaces and help prevent the growth of mold, mildew, and odors. Portable dehumidifiers can be moved to where they're needed. Ductable dehumidifiers can be installed into ducted HVAC systems to dehumidify all rooms that are connected to the HVAC system, or they can be used as freestanding dehumidifiers. Freestanding dehumidifiers stand on the floor and are suitable for applications where the dehumidifier will not need to be moved often.
