Keystone KSTE9721002 706 CFM Indoor Evaporative Air Cooler

Keystone evaporative air coolers, also called swamp coolers, are intended for use in hot dry climates where the humidity is low (less than 60%). Evaporative air coolers can lower indoor temperatures by as much as 15°F to 20°F by combining the natural cooling properties of water with a steady breeze from an efficient air moving system. Swamp coolers use nearly 75% less electricity than air-conditioners and use no ozone damaging refrigerants. Also, the water saturated pads act like a filter, removing dust and allergens from the air.
