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.
