Reverse osmosis (referred to as RO), which uses a special high-pressure water pump to increase the pressure of raw water, so that the raw water permeates through a reverse osmosis membrane with a pore size of only 0.0001 micrometers under the action of pressure. Chemical ions and bacteria, fungi, and virions cannot pass through, and they are discharged with the waste water. Only pure water molecules with a volume less than 0.0001 micrometer are allowed to pass, that is, pure water. Contains no minerals that are beneficial to the human body, which is not good for long-term drinking.
The source of minerals is mainly food rather than water. About 95% comes from food. Therefore, it is not a very reliable analysis of how harmful pure water is to the human body.
There are also fewer and fewer natural good water sources containing minerals, and more and more are natural water sources containing minerals but also industrial pollution.
No matter how you analyze it, drinking pure mineral water may be better than pure water among pure water, mineral water, and tap water, but pure water has no doubt a very large advantage over tap water. If a household can install an RO membrane water machine to filter tap water into pure water, it is still beneficial.
