The Air Cooler works by endothermic reaction (a reaction that consumes heat), so this evaporative Air Cooler sucks air through a wick saturated with water. As the air flows through the wick, some of the water evaporates into the air, consuming the heat that was in the air. An air stream is then blown out the front of the unit and has been cooled by up to 12ºF cooler than the current room temperature! This is not an air conditioner and therefore uses much less energy.
Note: The unit works well in dry climates; not very effective in areas with high humidity as the unit utilizes water to cool.
