In this paper, the ordinary tap water was changed into directly drinkable water successfully through filtration equipment, which was made by Cocoanut Active Charcoal and Nano Silver. The quality of filtered water was similar to Bama longevity village's water. Its properties were characterized by high-resolution superconducting NMR spectrometer, inductively-coupled plasma spectrometer, far infrared radiation rate tester, pH acidity meter and redox potential instrument. The results showed that the pH value of this water was 7.2~8.5, and the region of ORP was 70~150mV; It presented as 5 to 7 molecules structure of water clusters, can launch far infrared ray; It contained 16 macro and micro elements human needed, such as K
