To be honest, this thing is really useless, but it's just good-looking. don't look at the advertisements of those merchants.However, household water purifiers are really useful when they arrive, and water purifiers are divided into two categories.One is the ultra-filtration (UF) machine and the other is the reverse osmosis (RO) machine. The filtration accuracy of the UF membrane is 0.01-0.1 microns, which can only remove sediment, rust, most bacterial viruses and salt in water. The filtration accuracy of the reverse osmosis membrane is 0.1nm level. in addition to filtering the above substances, the salt in the water, various yin and yang ions can be removed. Obviously, the water quality of the RO machine is better than that of the UF machine. for a simple example, UF produces water equivalent to Nongfu mountain spring, and RO produces water equivalent to Yibao.
