The easy-to-use electronic buttons make it so much more convenient to use. Simply press the button of choice and allow the water to flow from the spout. The machine's highly efficient compressor makes the cold water crisp and ice cold at approximately 47° F without the need of adding ice cubes to your drink. The hot faucet is hot enough to cook one's tea or coffee or any other steaming hot beverage at approximately 185° F. There is a digital display with a clock as well as digital temperature control allowing you to adjust the hot and cold to your preferred temperature. The tanks hold 1 liter of hot water and 3.6 liters of cold water. There is a built-in nightlight making the water spout clearly visible in the dark. The dispensing area is 12x3.25x8.75 inches with 7.5 inches of space below the spout. This will accommodate most large cups or bottles. This water cooler is bottle-less with an NSF certified activated carbon filter (listed as model Avalon A4FILTER) and a sediment filter (listed as model Avalon A5FILTER) along with a water line that can be attached to your water source. The water is taken from your water source and filtered through the filters and then through the machines hot and cold water tanks. The filters will purify the tap water eliminating any chlorine, lead, rust, and bacteria.
