Mineral water is made by adding a small amount of mineralized elements on the basis of pure water. The appearance of this kind of water is mainly aimed at the conclusion that pure water does not contain minerals and long-term drinking is harmful to human health. With the intensification of the debate, this kind of water has a tendency to expand further. In recent years, many pure water producers produce mineral water at the same time to meet the needs of different consumer groups. However, because there is no national standard for mineral water, its quality can only be controlled by the enterprise's own enterprise standard. However, the types and contents of mineral elements in mineral water produced by different enterprises are different. Some enterprises even add chemical reagents directly into the water, and some enterprises use mineral concentrate with unknown sources. The safety and effectiveness of these additives have not been demonstrated, and the content has no scientific basis.

Pure drinking water refers to the water that meets the hygienic standard of drinking water and is treated by distillation, electrodialysis, ion exchange, reverse osmosis and other appropriate treatment methods to remove minerals, organic components, harmful substances and microorganisms from the water. According to different processing technologies, purified drinking water, also known as distilled water, pure water and space water, is the main product in the drinking water market. More than 90% of drinking water production enterprises produce pure water. Pure water is clear and transparent, and tastes good. Because pure water does not contain any minerals and its water quality is sour, whether it is the only drinking water in life has an impact on human health has always been a controversial topic among experts.
