Honeywell 300 CFM Portable Indoor & Outdoor-Compatible Evaporative Cooler

The evaporative air cooler offers an energy-efficient cooling option when the air is hot with low humidity, such as desert areas like the southwestern United States (recommended humidity level is 60% or less for maximum efficiency). 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, plug it in, and use. For outdoor use it is weather-resistant, UV protected and has an air-throw. For indoor use, a place near an open door or window in an area with adequate cross ventilation. This model also includes an extra honeycomb filter. For those living in more humid climates, consider portable air conditioning units or window air conditioners for indoor use.
