The Honeywell CO48PM Indoor/Outdoor Evaporative Air Cooler is the perfect choice to keep indoor rooms and outdoor environments comfortably cool and breezy. This weather resistant evaporative air cooler is made to resist outdoor conditions. Honeywell evaporative air coolers do not require power hungry components like compressors. The low power consumption translates into significant savings on energy bills compared to using air conditioners. Just unpack, add water/ice, place near open door or window, plug it in, and use. This unit is ideal for rooms up to 610 sq. ft. in any home or office. For outdoor environments, it has an air-throw up to 9.4 yards. Its powerful motor helps to deliver strong air flow while a 14-inch fan blade and 3-side honeycomb media keep performance optimal. A continuous water supply connection, 12.6-gallon water tank, and built-in overflow protection system allow long periods of unattended operation, making it perfect for more demanding applications.
