Yes, the unit has an automatic water cut-off when the water level is too low. However, what doesn't seem so optimal to me is the filter mats, which would have to be replaced regularly. Also beware of the beautiful air purifier words, a real air purifier achieves much more. The price also seems relatively high, because the mats also have to be replaced. A little simpler in principle, but also equipped with good features, this model could also come into question. It comes without recurring additional costs, because it has rotating discs and can be filled very easily from the top.
