Now at RC Willey you can save energy and money with the NewAir Portable Evaporative Cooler. Whether it’s your home’s central air or a window unit, standard air conditioning requires a great deal of electricity to create cool air, and they do so by using chemicals that are known to harm the ozone layer. They also require a lot of electricity to run, as anyone with a heart-stopping summer utility bill knows. An indoor portable evaporative unit, on the other hand, requires only enough electricity to run the fan and a bit of water each day to provide the natural cooling process. There’s no refrigerant at all, and the total electricity usage is about the same as a 100-watt light bulb. Available for Online Purchase Only. Assembly required. This product ships direct from the manufacturer, so RC Willey Delivery is not available. All-natural, eco-friendly cooling uses no harmful chemicals Energy-saving model uses 75 percent less energy than AC Oscillating fan covers up to 250 square feet
