The Honeywell CO25AE 52 Pt. Indoor/Outdoor Portable Evaporative Air Cooler offers an energy efficient option for cooling your home, workplace or outdoor living space in the most natural way. 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 cooling medium to large rooms in any home or office. Four fan speeds and oscillating louvers evenly distribute cool air through the honeycomb cooling media, while the carbon dust filter cleanses the air. The unit consumes 230 watts of power and includes an automatic shutoff timer. The electronic control panel is easy to use and the remote control lets you operate your cooler from across. It has four durable caster wheels which allow you to easily roll the unit from room to room.
