The Quest Dual 105 Overhead Dehumidifier is the world’s most energy-efficient dehumidifier: Using only 4.9 amps, the Quest Dual 105 removes 105 pints of water per day. It gives you the flexibility to hang the unit overhead or use ductwork and keep the dehumidifier in a different space entirely. Like all Quest products, the Dual 105 is made in the USA using the very best components and materials available.
