This evaporative cooler provides a natural way to condition the atmosphere. It cools by moving air through a surface composed of moist filters. The air temperature drops when the water in the filters transforms into gas. Humidity is not perceived, since the air in the room is renewed approximately every two minutes, providing a comfortable cooling effect.
