Magnetic Filter part Has many strong magnets to magnetize water by helix state. The part Forces +/- hydronium temporarily into cathode to exchange water molecule and mineral hydronium, makes Ca2+/Mg2+to unite electron, and has no cation function temporarily.

Hence, even heating, it doesn't unite hydronium---for example So42-, The part makes water not to scale any more.

Magnetic filter part makes water soft, and scale will be never produced in water pipe.
