Weak alkaline water is also called weak alkaline water and soda water. It can be formed naturally, or made of weak alkali effervescent tablets, soda effervescent tablets and machines. Weak alkaline water refers to water resources with PH value between 7.0 and 8.5. Weak alkaline water is filtered before it is decomposed by electrolytic water machine, so it is pollution-free water first. But more importantly, weakly alkaline water belongs to alkaline food, which can change unhealthy acidic constitution.

Six standards of good water

The World Health Organization (WHO) has put forward six standards for high-quality drinking water based on the analysis of a large number of survey results in the world's longevity areas:

1, the water does not contain bacteria, impurities, organic matter, heavy metals, etc. And it is pollution-free water;

2. The water contains a proper proportion of minerals and trace elements, and exists in ionic state, which is suitable for human absorption;

3. The 3.pH value is weakly alkaline, which can neutralize excess acid in human body;

4. Small molecular groups have strong water permeability and good solubility;

5. Negative potential can eliminate redundant free radicals in the human body;

6, containing the right amount of oxygen (about 5mg/L).
