Through RO technology, pure water machine removes bacterial, virus, scales etc. contaminants from water and produces fresh, sweet and drinkable water. However, at the same time, it removes many minerals from water. Another point to make is that, drink pure and clean water for a long period of time, although it is not hazardous to human body, it also reduces the body intake of minerals, not beneficial to health.
Another view is that, specialists consider that the purpose of drink water is to supplement water. There should be extra requirement for water. The minerals and nutrients required by human body should be supplemented by food. For example, doctors would never let people deficient in calcium to drink water with high scale. Their recommendation is to use calcium tablets or drink milk. And at the present time, there is no technology in the world that can guarantee to remove contaminants hazardous to human body from water and, at the same time, preserve substances that are beneficial to human body. Thus, we have option to ingest nutrients from food. And, we cannot select the drinking of dirty water and lead to slow hazards to human body. Thus, for health and safety, it is better to drink pure and clean water.
Both sides have reasonable arguments, we cannot make conclusion as yet. The consumers shall make selection in accordance to personal conditions. However, we can have a peace of mind that for those users that have installed water purifiers in home, there is one user has used for more than 8 years. No loose of hair and teeth conditions developed as yet.
