Purified water is the raw material that meets the sanitary standard of drinking water. Most harmful, toxic and odorous substances such as heavy metals, trihalomethanes, organic substances, radioactive substances and microorganisms are removed by various processes to eliminate the direct and potential harm to human health, and then bottled and sold to people for drinking.

The formation of mineral water is complicated. It refers to a series of physical and chemical actions such as leaching, anion exchange adsorption, biogeochemistry, etc. when groundwater flows through rocks containing different components. Trace and main components in rocks enter groundwater and are enriched to some extent, forming various types of mineral water.

2. Differences in composition.

Pure water is used to purify raw water by distillation, reverse osmosis and other technologies. While removing harmful substances, it also removes almost all trace elements and minerals beneficial to human body. It contains no impurities, is non-toxic and sterile, and is easily absorbed by human body.

Mineral water is different from tap water and pure water. It contains more than 20 kinds of trace elements and minerals such as lithium, strontium, zinc, iodine and selenium, and some are also rich in macro elements, such as gallium, magnesium, potassium and sodium plasma.

3. The difference between drinking methods

Pure water is water that can be directly drunk, and it has nothing to do with heating and boiling. Generally, drink cold in summer and drink more after heating in winter.

Mineral water is generally not heated, but can be heated slightly, preferably not boiled. Mineral water is ionic at room temperature because it contains a lot of macro elements such as calcium and magnesium and has a certain hardness. Calcium magnesium plasma is easy to form scale with carbonate after heating and boiling, so the best drinking method of mineral water is to drink it directly at room temperature.

Master Kong is called "mineral water", claiming that some minerals beneficial to human body have been artificially added to pure water. Later, TV reported that it was filtered by tap water. So it is not pure water, nor can it be called mineral water.
