Water filter

Hey, foreigners are not suggested to drink tap water. Boiling tap water is still useful. Some backteria in the water will be killed after boiling. If you are still worried, you can bring your water purifier. After purifying the water, you can boil it again to make sure that it is safe for you to drink.

Such information seems to be originated from hearsay and is very inaccurate. Where are proofs or sources of what is really the problem with water? Boiling is useless if the water is contaminated by heavy metals or toxic minerals. Purifiers are useless if the water contains bacteria.

I live in Bejing, but am originally from a highly developed country in Europe. For years, I have used Beijing tap water after first filtering it in a Brita filter, and then boiling it for coffee. For dishwashing and tooth brushing, I use it straight from the tap with no filtering. Same for rinsing vegetables for cooking. For rinsing berries, I rinse with filtered, unboiled, tap water. For just drinking plain water for thirst, I use my favorite bottled water.

A much bigger concern is the air. Buy a high quality mouth filter. Will save you from getting sick. Here is some of what Wikipedia ("Water management in Beijing") has to say about Beijing water:

"All tap water in Beijing meets quality standards" in 2012, according to Cheng Jing, head of the Beijing Water Bureau. Beijing drinking water quality standards "are based on the current standards set by the World Health Organization, the European Union, the US and Japan," according to Zhang Lan, a researcher at the Institute of Environmental Health and Related Product Safety under the Chinese Center for Disease Control and Prevention. Standards introduced in Beijing in 2006 cover 106 parameters, instead of only 35 previously, including pesticides, heavy metals and organic compounds.[19] Beijing was the first city in China to meet these new standards which became mandatory nationwide in 2012, according to Yu Yaping, official with the water authority.[20]

However, the tests are apparently conducted at the water treatment plants, not at the tap. Old rusting pipes cause a metallic taste and unpleasant smell of tap water in the south part of the city.[20] According to Ma Jun, director of the Institute of Public and Environmental Affairs, drinking water is recontaminated in the old distribution network spanning 1,900 km."

Your statement regarding water purifiers not removing biological pathogens is completely false. We live in Beijing and use an RO unit to remove not only heavy metals but water born parasites such as giardia. It is an essential part of maintaining our health in CN especially as purified water is often 'fake' here.

Boiling the water in China wouldn't get rid all the heavy metal in it,But kill it enough of the germs also dalute of the heavy metal contents of the water.Wouldn't make you sick or have very bad diaeria in your abdominal stomach intestines vaules.
