Bottled water is available in white, blue and green caps, do you know what these colours mean?
1. White caps
Bottled water with a white cap is not mineral water, but filtered drinking water or drinking water. Generally speaking, bottled water with a white cap is made from water that meets the hygiene standards for drinking water and is filtered of harmful substances, minerals and trace elements that are beneficial to the human body.

Water with a blue cap is Natural Mineral Water (NMW), which is usually naturally gushing from deep underground or collected from drilled wells, and is filtered, purified and activated by the bottom layer over the years, and is rich in minerals. Drinking too much mineral water can affect the production of gastric juices for digestion. The minerals in mineral water can also irritate the kidneys and bladder, increasing the burden on the kidneys and bladder.
3. Green caps
Bottled water with a green cap is Mineral Water, which means that minerals are artificially added to pure water, sterilised and then filled.
