This isn't a watered-down version of a bigger dehumidifier - it's a highly effective mid-size machine in its own right, built around the powerful and whisper-quiet Peltier technology. Peltier technology works with no moving parts, so we managed to design our dehumidifier as a compact appliance: small, lightweight, low on energy consumption, powerful, effective at drying up musty rooms, and, with all that, a long lifespan. Suited for spaces up to 2,200 cubic feet, our mid-size dehumidifier is the perfect tool to extract moisture and dust particles from stagnant areas and mildew- and mold-stricken rooms. From bathrooms to laundry rooms to bedrooms to antique cars to boats, it rids the air of mustiness and unpleasant odors while quietly pulling in excess humidity at a rate of up to 25 ounces per day at 86å¡ Fahrenheit and 80% relative humidity. Another advanced function is the auto humidistat. Dehumidifiers without a humidistat work hard non-stop even if RH levels drop as low as 20%. This wastes energy and wears out the power adapters. With the humidistat function, you can set your desired relative humidity level in the range of 40%-80%. When RH levels increase beyond your set level by a value of 5%, the machine automatically turns on. When RH levels decrease below your set level by a value of 5%, the machine automatically turns off. Default setting is 50% RH. A removable water reservoir with a capacity of two full liters spares you the hustle of emptying out an overflowing water tank every day. It can hold approximately 2.5-days' worth of dehumidifying action. It is also programmed to shut off automatically once it has reached capacity. An indicator light will go on to remind you to empty the tank out.
