Overview
The Quest Dual 155 dehumidifier is one of the most energy-efficient commercial dehumidifiers on the market today. Removing 155 pints of water per day, this unit can save you thousands in energy costs every year compared to the competition. It gives you the flexibility to hang the unit overhead or use ductwork and keep the dehumidifier in a different space entirely.
