Acheive perfect tempertatures in any room with this high quality cooler. This Evaporative Air Cooler, Humidifier and Fan is versatile, lightweight and economical. The Cooler easily rolls from room to room for use anywhere in your house or office. This Air Cooler shoots a stream of air with oscillating louvers, to evenly distribute refreshing cool air. The Air Cooler works by endothermic reaction (a reaction that consumes heat), so this evaporative Air Cooler sucks air through a wick saturated with water. As the air flows through the wick, some of the water evaporates into the air, consuming the heat that was in the air. An air stream is then blown out the front of the unit and is considerably cooler than the current room temperature. This is not an air conditioner and therefore uses much less energy. The Cooling Pad is made of cellulose paper, impregnated with unique ingredients for high performance and structural strength. Treated with special stiffening and wetting agents for maximum water absorption and retention; and with Anti-Rot chemical for prevention of algae and bacteria growth. Due to the 3-dimensional, weaving structure of the Cooling Pad, there is longer contact between air and water. Features a 3-D Honeycomb Cooling Pad and remote control. Air coolers are designed for spot cooling. This unit is best used in dry climates or open spaces. Leave window/door open to limit the rise of humidity and for better air ventilation in the room. Add as much ice as possible and set unit next to you for best effect.
