The Essick Air 4DTS 300 is designed to humidify an entire house-up to 2,700 square feet. Using an evaporative system and unheated, natural, evaporated water, this humidifier requires less energy than warm mist or steam units. You also won"t have to deal with white dust, spray, or mist on furniture or floors. Other benefits of the evaporative system include: relief from symptoms of dry skin, itchy eyes, chapped lips and scratchy throat; it prevents plants and furniture from becoming overly dry; and reduced static electricity protects computers and electronics. This humidifier"s water bottle holds 5.5 gallons and disperses up to 13 gallons of water per day, refilling easily and neatly in the sink via an included hose. Cleaning the rest of the appliance is just as simple: the power unit lifts off the top of the humidifier for easy cleaning and servicing, while the evaporative wick, which filters out mineral deposits, also lifts out for replacing.
