To avoid problems caused by moisture, such as structural integrity deterioration, or an unhealthy workplace environment, a dehumidifier is necessary to maintain EPA recommended relative humidity levels between 45-50%. Only supplemental dehumidification provides indoor humidity control regardless of air conditioner operation or outside moisture conditions. The Quest 105, 155 and 205 Dual plug-n-play dehumidifiers are among the MOST energy-efficient large capacity dehumidifiers on the market today. The Quest 155 Dual for example, exceeds Energy Star standards by 60% with 80ºF/60%RH using 8.0 amps/115V. The Quest Duals' horizontal configuration, patent pending dual outlet design, and insulated cabinet for quieter operation enable their exceptional performance in almost any application. These units are also optimized for low heat load, so they will continue to control humidity even when it is cool and humid outside. The Quest Duals are plug-n-play, requiring no installation. Optional condensate pump and ducting kits provide the ultimate in flexibility for the most challenging space restrictions and specialized applications. Quest 105, 155 and 205 Dual dehumidifiers will continue to protect your structure and control the inside environment, ensuring superior indoor air quality and the comfort of its occupants year round. MERV-11 filtration is standard on these units, capturing particles (including mold spores) down to 1 micron in size. The Quest 155 Dual provides water removal of 155 pints per day at 80ºF/60%RH using 8.0 amps/115V. Compared to most standard dehumidifiers (7.3 pints/kWh), the Quest is nearly twice as efficient, standard unit just can't compare. The Quest 155 performs at 7.3 pints per kilowatt-hour Estimated annual electrical savings: Quest 155 Dual — $1,213 Features: Industry-leading efficiency, most efficient on the market today Plug-N-Play Patented, optimized air-to-air heat exchanger High-efficiency, long-life impeller fan Quiet operation a
