Tristar Air Cooler 7L AT-5470BS Portable Digital Fan Conditioner Timer Ice Packs

The Tristar 7L Digital Air Cooler uses cold water to cool the airflow so you can bring down the temperature by a few degrees and enjoy a refreshing breeze. A big advantage of the Tristar air cooler over an air-conditioner is that you will not have to struggle with a hose or have to make a hole in the wall. Air coolers are also more effective than a standard fan. The air cooler is portable because of its sturdy castors, just fill the reservoir up with water and plug it in. The Tristar air cooler uses cold water to cool the air and comes with 2 ice packs which you freeze over night and then add to the water tank.
