This Honeywell CL25AE indoor evaporative air cooler features Honeycomb Cooling Media technology to ensure optimal cooling performance and a noncompressor system to provide an energy-efficient design. The oscillating louvers disperse cool air evenly. Note: This unit is not an air conditioner and does not have a compressor or condenser inside. Evaporative coolers are designed for spot cooling and will not lower a room's ambient temperature. This unit is best used in dry climates or open spaces. Keep a window or door open to limit the rise of humidity and for better ventilation. Add ice to the tank and set the unit near you for optimal results.
