A:Answer Hi, Evaporative Air Coolers are great for providing spot cooling. They cool the air through water evaporation and the cooling effect is best when the relative humidity is low (under 60%). The cool air surrounding the air cooler can be reduced by 7-15 degrees Fahrenheit in dry climates and in a room with adequate cross-ventilation.
