Inverter air conditioners use the within coil temperature sensor to keep the evaporator as cold as attainable. When the evaporator is just too cold, the compressor is slowed or stopped with the indoor fan running.

A washable carbon filter keeps the room’s air cleaned and three fan speeds facilitate with circulation. However, it is important to note that the unit’s cooling ability and noise levels are subjective to the climate of your country and its level of urbanization.
