Active Water Device "νG7 (New G Seven)"

Active Water Device "νG7 (New G Seven)"

A water revitalizer that transforms water into highly functional water (quantum water) by passing it through a stainless steel field converter, charging the electrons.

The "νG7 (New G7)" is a quantum water device that requires no maintenance. When water (H2O, dihydrogen oxide) passes through this product, the hydrogen bonds of the water affected by magnetic and weak electromagnetic fields within the hexagon field converter loosen, partially ionizing it and activating it as high-energy potential water that contains oxygen and hydrogen in gas form. The activated water has increased dissolving power and permeability, making it noticeable in phenomena such as water boiling more easily, plants thriving, and oil stains being easier to remove. 【Features】 ■ Obtained Japanese Patent No. 4063768 ■ Sterilization and deodorization effects ■ Increases lactic acid bacteria ■ Improved surfactant power ■ Generates trace amounts of hydrogen ■ Cost-effective with no expenses required after installation *For more details, please download the PDF or contact us.
