The Whirlpool 155 CFM indoor evaporative air cooler offers an effective, low cost cooling option in areas with dry heat, such as the southwest region of the United States. The low power consumption of a mere 70 watts will save you a noteworthy amount on your energy bill in comparison to the cost of running a standard air conditioner. This swamp cooler is designed for indoor use in open environments equipped with cross ventilation up to 428 square feet. Control the operation of your air cooler with ease using the LED display or convenient remote control to adjust the function to suit your comfort needs. Three fan speeds and automatic horizontal and vertical oscillation louvers evenly distribute cool air after it is sifted through the filter, providing a fresh, clean breeze throughout your room. The horizontal louvers also close when powered down. A clean filter indicator light will turn on after 100 hours of cooling system usage so the evaporative cooler can continue running smoothly. Caster wheels and a convenient handle allow for effortless movement between rooms. For those living in more humid climates, consider Whirlpool’s portable air conditioning units or window air conditioners.
