Before summer gets here, you need to add a little more cool to your home without having to worry about running your AC too low. The Kool-Down Evaporative Air Cooler cools and circulates moist air within a seven-foot area and is just perfect for any room in your house because it’s quiet and portable. Just add ice water to the 10-hour water tank for ultra-cooling action. It has a two-speed fan with adjustable air vents. It requires four C batteries (not included).
