The Nikken solution in the search for perfect water. The Nikken PiMag Optimizer II uses the same forces as those found in nature - magnetic energy, water agitation, pi technology - to produce water that is optimized, ideal for any use. A revolving pair of 4,400-gauss magnets produces a complex magnetic field – a cocoon of magnetism. The pi ring inside the pitcher exposes the water to natural minerals and coral calcium as the rotor creates a vortex (cyclone) pattern, adding oxygen.
