Honeywell 830-CFM 2 -Speed Outdoor Portable Evaporative Cooler for 460-sq ft (Motor Included)

Honeywell Evaporative Air Coolers are an environmentally friendly and cost-friendly cooling option for your home. Much like a breeze flowing across a lake or the refreshing cool air you feel near a waterfall, air coolers produce a comfortable, cool breeze through the natural process of water evaporation. This no-compressor system cools naturally, efficiently, and inexpensively. Evaporative air coolers are more effective in areas with a maximum relative humidity of 60% or less. Warm, dry air is important for more effective evaporative cooling and the temperature decrease will be greater in drier environments because higher evaporation occurs when the humidity is low. Evaporative air coolers produce moisture and can be used to increase humidification in a room. For indoor use, place near an open door or window with adequate cross-ventilation. Evaporative air coolers are not air conditioners, and they do not use a compressor or refrigerant gas. Air coolers should not be expected to cool as efficiently as a refrigerated air conditioner. For those living in more humid climates, consider Honeywell Portable Air Conditioners. Air coolers may not be a sufficient cooling method in a heat wave.
