Mimic the comfort of a cool lake breeze in your home with the slim Honeywell 470-588 CFM indoor evaporative air cooler, built to cool small to medium rooms up to 280 square feet. Living room, bedroom, play area or office—the unit is lightweight and adapts for summer heat or winter dryness.. The tower design with oscillating louvers allows for the airflow to be distributed evenly, while the slim design makes it convenient to fit comfortably into compact spaces. The washable dust filter and easy-access honeycomb cooling media make for easy upkeep, while the remote control lets you control the unit from across the room. 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). For those living in more humid climates, consider portable air conditioning units or window air conditioners.
