Experts: Not recommended water purifier water most scientific classification
For this, Miss Zeng Xuancheng Beijing Health drinking water Professional Committee chairman Zhao Feihong "20 years not to drink tap water" that: tap water detected strong carcinogen NDMA, because the dose is still small, does not mean that drinking will cause cancer, but water pollution is not just a question of NDMA, heavy metals, eutrophication , antibiotics, drug residues, pipelines and other pollution have plagued tap water.
According to Ms. Zhao Feihong introduced: the early years, in order to deal with pollution, people began to use a water filter. But then the development of scientific proof, water filtration water purifier, water is acidic, long-term drinking is not conducive to human health.

For some people use bottled mineral water for cooking, Zhao Feihong think that in fact this is not a luxury, a few dollars a day also. And only the health of their families, the real savings. Healthy natural mineral water than tap water, but the key is to eliminate the contamination. Cooking tea, etc. To enter the body of water, mineral water; and bathing, washing dishes, which do not enter the body of water, then with tap water. This classification method with water, very scientific, totally worth promoting.
