Abstract
A steam generating humidifier apparatus (1) comprises a water container (2) with a water inlet (11) and a steam outlet (12) and at least two elongated electrodes (3, 4) arranged vertically within the container. The electrodes have each an upper electrode end (3′, 4′) and a lower electrode end (3″, 4″) and at least one of the electrodes is provided at its lower electrode end with an end piece (15) made of an electrically non-conducting material which end piece is connected to the lower electrode end. This will avoid arcing between the electrode and the water surface in cases where the water level drops so low that the electrodes are exposed.
