To understand bottled water, we need to be clear about the classification of water

Pure water, which is made by distillation, deionization or ion exchange method, reverse osmosis method and other appropriate processing methods, is water that meets the sanitary standard of drinking water and is sealed in a container without any additives, and the water is made by distillation, deionization or ion exchange method, reverse osmosis method and other appropriate processing methods, and is sealed in a container without any additives. Water that can be consumed directly.

Natural water  refers to surface water or groundwater (mainly including well water, spring water, mountain stream water, deep reservoir (lake) water) as raw water, which is treated only by the necessary filtration, ozone treatment or other equivalent disinfection process. Water that is directly drinkable without any chemical additive and sealed in a container, the source of which shall not be subjected to any chemical treatment (e.g., adding chlorine, bleach, etc.) from public municipal water supply systems or municipal water supply systems.

Mineral water is based on pure water, added minerals and other food additives of water. The kinds of mineral water added are confused and there is no uniform national standard. The main purpose is to replenish water, not nutrition. Because there is no national standard, mineral water produced by different enterprises has different mineral types and contents.

Natural mineral water is water that is naturally gushed out or drilled from deep underground, contains certain amounts of minerals, trace elements or other ingredients, is unpolluted in a certain area and takes preventive measures to avoid contamination. Its chemical composition, flow rate, water temperature and other dynamic indexes are relatively stable in the range of natural periodic fluctuations.
