Quite simple and effective. It functions as a room humidifier or as an air freshener, with the addition of essential oils or aromatic burning oils. The intensity and effectiveness of the room fragrance depend on the quality and quantity of oils used each time. It doesn't make any particularly loud noise, as I read in another review, or it simply doesn't bother me. It is almost silent

It has an effect on scenting the space but it makes incredible noise. We only use it when we have guests or when we are moving, and even when we turn it off, we let out a sigh of relief. I would not recommend it in any case... after not even a month, it completely broke down... unfortunately, wasted money...
