How about American ke qi water purifier? Is the quality of the water dispenser of Ke Qi reverse osmosis direct drinking filter not good? It is recommended that you first understand the two major technologies of the current water purifier industry: 1. reverse osmosis. 2. UF. Reverse osmosis is currently recognized as the safest and most scientific water treatment technology in the world. The water base through the reverse osmosis membrane is pure water, that is, only water molecules, so it is the safest, so the reverse osmosis machine is also called a pure water machine. The filtration accuracy of UF is tight and reverse osmosis, and the pure water is not produced. because the pore size of the UF membrane is larger than that of reverse osmosis, some manufacturers promote that the UF water purifier is a water purifier that can retain minerals. In fact, it is light to avoid weight, since it is not pure water, there may be bacteria, viruses and chemical pollutants with a diameter smaller than the pore size
