30-Liter Indoor Evaporative Air Cooler (Swamp Cooler) with WiFi Function in White
X
Overview
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 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. Buyers Note:For those living in more humid climates consider using Keystone portable air conditioning units or window air conditioners.
