I want to install a water purifier, but I want to retain the minerals in the water.

The worst of the water purifiers is the water purifier, the other water purifiers all retain minerals. Water purifier is a reverse osmosis membrane over the water machine, that is, OR membrane water machine, the production of water is pure water, does not contain minerals, because the reverse osmosis membrane filtration precision is 0.00001 microns, only a small number of water molecules can pass through the reverse osmosis membrane, so it is necessary to install a pressurized pump, that is, to plug in the electricity, the water and electricity in the together with the security of it is not the main reverse osmosis membrane filtration of tap water, then, only 30% of the Water can pass, the rest of the water are treated as waste water is excluded. This is not the most important, the main thing is, pure water against the three laws, one is against the law of human evolution of human evolution for 3 million years, drink is a water solution rather than pure water, the second is against the laws of nature, there is no pure water in nature, water and ions with the existence of the third is against the laws of science, there is no scientific paper in the world to recognize the pure water is good water. Pure water has no minerals, and often drink pure water will also take away the minerals in the body. And pure water is a macromolecule.

The real good water machine should be able to produce ecological water (also called high-energy too live water), that is, China's longevity village of Guangxi Bama shrinking drinking water. Good water has seven standards, 1, clean and pollution-free 2, small molecule group 3, PH value is weakly alkaline 4, dissolved oxygen in the water following the moderate content of carbon oxides 5, the water is rich in minerals and trace elements needed by the human body 6, the water is moderately soft and hard 7, the water's physiological function is strong. To achieve the first standard to have a filtration device and sterilization device, filtration is not very easy, because a lot of things in the water is very difficult to filter out, such as heavy metal pollution, if there is no KDF, cartesian these two cartridges can not be completely remove the clean, you want to buy this water machine does not have a sterilization device, the bacteria are alive, if not killed will grow, now the best sterilization device is iodine catalyst, it The best sterilization device is iodine catalyst, which can be released by bacteria, instant sterilization. The 2nd, 3rd, 4th, 5th and 7th standards should have an activation cartridge, that is, to activate the dead water into real spring water. The sixth standard, that is, the soft hardness of that is to have Bayer ion exchanger (also known as cation exchanger) the cartridge can be excess calcium and magnesium ions in the water into the human body needs zinc. And so on.

That is to say, buy a water machine to look at the main material, do not look at the brand, a lot of big brand water machine is the concept of hype, inside the material is not up to the standard of good water. You can turn around the mall to see the water machine cartridge materials and then go online to find out what they do, can not reach the standard of good water on the line.
