Sunpentown SF-613 LED Evaporative Air Cooler

This Evaporative Air Cooler, Humidifier, Air Filtration and Fan with Ionizer is versatile and an economical way to cool and humidify the surrounding air. Designed with micro-computer control system, this unit can lower surrounding temperature and humidify the air through the principal of water evaporation. The Cooler easily rolls from room to room with lockable casters. This Air Cooler shoots a stream of air with oscillating louvers, to evenly distribute refreshing cool air. Can also be used as a fan or humidifier if temperature is not an issue. The remote control allows you to easily change settings.

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.

Note: The unit works well in dry climates; not very effective in areas with high humidity as the unit utilizes water to cool.
