Does not replace a 100% air cools but good anyway. The air is very fresh and if you stay too long before you're cold. A pale fan is very tiring as there was the impression of being outside with a light breeze. Moreover, it is very quiet. I have already put the night to refresh me and I could sleep despite the hot weather. I've never set higher than 4 on a scale of 10 and is more than enough for a room of 20 m2. It is also vacillating and sweeps the room of all its freshness. Furthermore it can be programmed when we fall asleep so he stops by itself. Installation is very simple and its use also. It is very light and takes in every room. Well, anyway you understood: it saves my life and worth every penny.
