The Honeywell CS10XE 21 Pt. Indoor Portable Evaporative Air Cooler offers an energy efficient option for cooling your home or office during hot and dry conditions. Honeywell evaporative air coolers do not require power hungry compressors. The low power consumption (only 100 watts of power on low) translates into significant savings on energy bills compared to using air conditioners. Just unpack, add water, place near open door or window, plug in and use. This unit is ideal for cooling a room up to 175 square feet. Four fan speeds and oscillating louvers evenly distribute cool air through the honeycomb cooling media while the carbon dust filter cleanses the air. The electronic control panel is easy to use and the full-function remote control with onboard storage lets you operate your cooler from across the room. *Note: An Evaporative Air Cooler does not use a compressor or refrigerant gas so it should not be expected to cool to the same degree as a refrigerated air conditioner.
