How big of an area will the Quilo 3in1 cool?

The Quilo 3in1 is a spot cooler, meaning it will cool within a specific radius. Your worktable, bed, couch, breakfast nook. Its effect should be felt within 130 sq. ft. Bear in mind that evaporative cooling is not air conditioning, and is highly dependent on your climate. It will work best in hot regions with low humidity.
