Swamp Air Coolers work by using evaporation to cool the air in your room – similarly to how a cold towel on your head feels great in summer! The air cooler draws water across air cooler pads. The fan then draws dry, hot air into the machine and through the cooler pads. As the hot air crosses the pad, the water molecules evaporate and cause the air temperature to drop – often by as much as 20°c. The fan then blows this cooled air into your room.
Evaporative air coolers have 2 major advantages when compared to traditional air conditioners: energy efficiency and sustainability. Evaporative air coolers use up to 7 times less watts of energy than an air conditioner, and use water rather than a liquid refrigerant. Using less electricity lowers your carbon footprint and saves on your energy bills, and chemical refrigerants are harmful to the ozone layer.
