Warning, this device does not work with distilled water and is unfortunately nowhere here that I had actually allowed to return one and then the replacement device the same problem, namely that it did not concern. Even the dealer knew nothing about it and we even searched together on the phone after the solution because they actually have even tested the equipment sent back. the care was so really very personal. only then I got it, to try it with plain water, so tap water. since the refill tank inside is not clean because it is filled only through a hole, I wanted to avoid calcium deposits and use distilled water. but now I have to stop to see how quickly it calcified. they write they should descaling agent under any circumstances use or acids (vinegar), so how to solve the then? but for the price I would say I can if it must be to buy me in two / three years a new. I find the atomizer effectively, noise and also very pretty. However, I have several tested equipment for my job (aromatherapy in nursing homes) and definitely found some that are easier to use, we then ordered wholesale. but they are somewhat weaker in the wirkung..also I keep these for home.
