This mobile air cooler is an efficient portable fan that can inexpensively lower the air temperature and improve the indoor air quality of medium-sized rooms. 

This mobile air cooler combines ventilating and air cooling functions and delivers a stream of cool air to the room. The cooling effect is achieved by the evaporation of water or ice from the 8-litre water tank. It differs from conventional fans as it is designed to humidify and purify the air in order to improve the indoor environment.
