The Honeywell CO25MM outdoor air cooler is a great choice to keep indoor rooms and outdoor environments comfortably cool and breezy. This weather resistant evaporative air cooler is made to resist outdoor conditions, great for spot cooling in both home and commercial locations such as your backyard, garage, a retail shop space, office warehouse and even outdoor restaurant areas. Honeywell evaporative coolers do not require power hungry components like compressors. The CO25MM consumes only 190 watts of power. This low power consumption translates into significant savings on energy bills compared to using air conditioners. A continuous water supply connection, 52 pint (6.6 gallons) water tank, and built-in overflow protection system allow long periods of unattended operation, making it perfect for more demanding and commercial applications.
