Quest 205 HIgh Efficiency Dehumidifier

Quest 205 High Efficiency Dehumidifier – 200 Pints/Day | 120V | Compact, Powerful, Plug-and-Play Design

The Quest 205 is a serious performer in a compact package. It’s the most powerful 115V dehumidifier Quest makes, pulling 200 pints per day at 80°F and 60% RH—yet it plugs right into a standard outlet. That means no special wiring needed, just plug it in and go.

Built as the little brother to the well-known Quest 225 and 335, the 205 takes things up a notch with M-CoRR™ Technology—a patented multi-coil system that recycles energy during operation, giving you a 30% capacity boost and better efficiency all around. At 7.7 pints/kWh, it’s one of the most efficient dehumidifiers in its class.

It’s also designed with real-world growers and operators in mind. The onboard digital controls are easy to use, and if you want to wire it into your system, it has a low-voltage terminal block too. Hang it overhead with the built-in handles and hanging points, or keep it on the ground—it works both ways. And when it’s time for maintenance, just pop off the side panel without removing the unit from the ceiling.

Like all Quest equipment, the 205 is engineered and assembled in Madison, Wisconsin, and backed by a 5-year warranty. It’s efficient, compact, and built to last.
