If going natural is on your mind...then the Eco-Friendly water Cooler is an ideal product, that will give you chilled water without using any electricity, apart from filtering it off all the chlorine and pesticides.
The water cooler uses the power of gravity to do that. Just pour in two gallons of tap water into the cooler and it falls through a carbon filter that cleans the water and Evaporative cooling technique chills the water. The temperature of water inside a hand-made terra cotta cooler is 12-14 degrees cooer than the room temperature. I think this cool water is just right to keep your throat in good condition.
