The Cool-A-Zone evaporative cooling works by utilizing the power of evaporation to cool air temperatures. When water begins to evaporate from liquid to gas, it will lead to a drop in air temperature. Harnessing this scientific principal, Cool-A-Zone evaporative cooling can drop the air temperatures up to 25 degrees!

The Cool-A-Zone CoolBox has a thick pad inside of the evaporative cooler that is designed to saturate when it  absorbs water so that as hot dry air is drawn into the cooler, it crosses the moist pad allowing the water molecules on the surface to evaporate which then cause the temperature inside the cooler to drop. As the fan spins to draw air into the cooler, it then pushes the cooled air back out quickly cooling the area around.
