A device is provided for the treatment of water so as to reduce or remove micro-organisms therein as well as possible other causes of skin diseases or waterborne diseases in human beings and animals. The device comprises at least one permanent magnet provided with an axially extending opening, said magnet subjecting passing water to a magnetic field and being made of a magnet material presenting an energy product of more than approximately 20 and preferably more than approximately 40 kJ/m3and a coercive force of preferably more than approximately 200 kA/m at 25° C., the north pole of said magnet being positioned at one axial end face and the south pole at the opposite axial end face, and where the water is passed through the axially extending opening in the magnet. Moreover, a method of treating the water is provided, whereby the water is allowed to pass said device immediately before or adjacent a tapping point.
