It is one of the trusted Air-conditioning Brands from the hands of Samsung. It cools the whole room with even distribution -of air in every inch of your room whatever was the width of the room each & every corners will be cooled.
But my advise is that in larger rooms it is better to turn Samsung BIO Sleep ON about Ten minutes before you go to this room because Bio Sleep needs some time to reach the whole room. The main advantage is the energy saving.
You will be surprised with the great decrease in the Electricity use in your electricity Bill when you compare before and after Samsung Bio Sleep.
