软化器以前不都是用盐,把CA和MG置换成NA的么,
不就等于把好好的矿泉水去掉矿物,加把盐进去么

Water Softeners
Household systems reduce the hardness of the water by replacing calcium and
magnesium with sodium or potassium, depending on the type of softener.
Installation of a water softener, however, is strictly an issue of personal
preference and should be done only out of aesthetic concerns, not because of
fears about water quality.
Advantages of water softeners include improved "feel" on skin when bathing,
longer life of appliances and reduction of water spots and deposits.
Disadvantages include potential health risks from sodium intake, harm to
houseplants due to elevated salt content and overload or reduced
effectiveness of septic systems.

早就有定论,软化水弊大于利。好处主要是管道,水池,电器。不容易留水渍,看着好
看。对人体没什么好处

软水滑是因为里面没有残留的矿物质。
所以硬水才会在皮肤上留下东西,而不是软水。
用软水洗东西比较省肥皂也是因为没有矿物质中和。

其实软/硬水挺神奇的:
Fact: Soft water is water containing low levels of hardness ions. Yet, water
like distilled water, reverse osmosis water, de-ionized water, rain water
et cetera does not produce the slippery effect on your skin, even though all
those types of water contain virtually zero hardness minerals.
Water that has been chemically softened by the ion exchange process used by
a salt based water softener removes the so-called “nuisance minerals” (
often defined as calcium, magnesium, iron and manganese) because they can be
associated with staining and scale formation. These minerals occur
dissolved in water as bivalent ions. During the “softening” process each
of one (1) these nuisance mineral ions gets replaced by two (2) sodium ions
(or potassium ions depending on the type of salt used during regeneration).
The by product of this process it the creation of a proportionate amount of
sodium bicarbonate (baking soda) in the water. The harder the raw water, the
slicker the softened water. Sodium bicarbonate is a surfactant which
imparts a soft or slick feel to the water. Please demonstrate to yourself:
add baking soda to water with virtually any hardness – and the water will
feel soft.

小时候在下雨后形成的泥巴坑里游泳,也没觉得滑啊还是不滑的,
