Frigiking 1000 sq ft Portable Window Evaporative Cooler 4000 CFM

This evaporative cooler, which is made in Phoenix, AZ. is designed for use in dry climates where it draws hot outside air through a wet aspen pad, dropping the air temperature as much as 20 degrees. These saturated pads also filter the air removing dirt and allergens. While this product cools the air it is very unlike air conditioners because it can use up to 75% less electricity and uses No ozone damaging refrigerants. And unlike an ac unit the cooler is easy to install and maintain.
