A misting fan blows a fine mist of water into the air, absorbing heat from the air and causing it to evaporate. In this way, the misting fan works like a humidifier and air conditioner using the principles of thermal dynamics and evaporative cooling. The fan circulates the cooler air caused by evaporation. A misting fan can be used indoors and outdoors, and is especially ideal in dry climate. It can also be used in a greenhouse to provide a higher degree of humidity for thirsty plant species.
