水硬的话要先装软水器，软化水对正常人来说也许盐含量还可以接受，但是还是不太好，所以还要再装ro反渗透过滤器。对环境而言，软水器很不环保的，也许水硬点就硬点吧。

我也想了解水硬的问题，除了喝水有味，水垢这种视觉上的不舒适，对健康是不是没有什么影响？

Hard water is not a health hazard. In fact, the National Research Council (National Academy of Sciences) states that hard drinking water generally contributes a small amount toward total calcium and magnesium human dietary needs. They further state that in some instances, where dissolved calcium and magnesium are very high, water could be a major contributor of calcium and magnesium to the diet.

Researchers have studied water hardness and cardiovascular disease mortality. Such studies have been "epidemiological studies," which are statistical relationship studies.

While some studies suggest a correlation between hard water and lower cardiovascular disease mortality, other studies do not suggest a correlation. The National Research Council states that results at this time are inconclusive and recommends that further studies should be conducted.
