The product smells real bad after first activation. Even after washing the tank the mist it produced really smells bad and the air cleaner in the same room but 7meter away respond to it that the air was heavy polluted. I had the idea to order an other 2 but after this one I don't want the same. After 10 hours of use the mist don't smell that bad anymore and also the air cleaner don't respond that heavy any more on this device. But it isn't usable directly after shipping. It must run 3 tanks of water outside any room where you also use the air to breathe before it is usable. So I won't recommend this product. It looks nice but I want to keep my children safe so if it smells bad. The air cleaner thinks the air and mist it produced is polluted I don't trust it in the bedroom with my children.
