Misting systems work by evaporating fine water droplets into the air surrounding target areas that require cooling. A properly installed mist system creates a curtain of mist around all open-air sides of a structure. Mist cooling can reduce temperatures by as much as 30°F depending on the efficiency of the misting system, relative humidity, and outdoor temperature. Mist cooling allows the use and enjoyment of outdoor living areas that normally would not be used when temperatures begin to rise.
