DescriptionFeeling the heat? Check out the EvaChill EV-500, the newest model from Evapolar. This ultra-lightweight and energy-efficient personal air conditioner features patented EvaBreeze® material, which improves efficiency while remaining entirely eco-friendly and biosafe. EvaChill's easy to use. Just fill the water tank, connect to a power supply, and the cartridge will absorb large amounts of water. The water spreads evenly through the cooling pads while air blows through them, evaporating the water to lower the air temperature around you. No heat exhausted at all. The natural evaporative cooling effect can drop the air temperature up to 59º in just 10 minutes, ensuring you can always keep your cool.
