Whether it is tap water or municipal water, it cannot be directly drunk. Taking tap water as an example, after it is introduced into the main pipeline, it is pre-filtered to remove large particles, then the whole-house filtration system is used to remove small sediment, and finally it is divided into pipes and enters the kitchen, toilet, etc. for daily use. But the water filtered by the whole house system still cannot be directly drinking, and most families use the under sink RO system to obtain pure water.
1. How many levels of filtration does the under sink RO system have?
The tank under sink RO system is divided into 5-stage, 6-stage and 7-stage. The configuration of 5-stage under sink RO system is the same as that of 6 and 7 stage under sink RO system. The 6-stage RO system adds a mineral alkaline ion filter, and the 7-stage under sink RO system adds 2 mineral alkaline ion filters. The purpose is to supplement the minerals needed by the body. The RO membrane of under sink RO system can effectively reduce the TDS of water, and also take away some minerals in the water. Therefore, the improvement of adding alkaline mineral ion filters has been made in both the 6th and 7th stage under sink RO system. Bestpure/Yunda's under sink RO system can choose RO membranes that meet local drinking water filtration according to customer needs and select under sink RO system with different filtration stage according to the situation.
2. What substances can the under sink RO system function remove from water?
PP spun filter is the first of under sink RO system, which removes large particles of impurities, rust, sediment, red worms; activated carbon filter is the second, removes odor and absorbs chlorine in water; the third is block activated carbon filter can absorb residual chlorine, odor, pigment, remove organic chemicals, residual pesticides and other chemicals. The Under sink RO system fourth filter is reverse osmosis membrane, the pore size of the permeable membrane is 0.0001 micron, which can effectively remove bacteria, viruses, heavy metal ions, pesticide residues and other harmful substances in water. Activated carbon filter is the fifth of under sink RO system can absorb different colors & odors in the water, adjust the taste of pure water, can be directly drunk; The last alkaline ceramic filter of under sink RO system is used to adjust the pH, 8-9, and release minerals that are beneficial to the human body.
3. Is the filtered water of the under sink RO system enough to replenish the minerals needed by the body?
Experts point out that water is one of the main substances that make up the human body. The main role of water in the human body is metabolism, and drinking water is not the main way to provide the nutrients needed by the human body. Natural water contains a certain amount of minerals, but the contribution to the minerals required by the human body is minimal. In fact, only living plants can absorb and utilize inorganic minerals from the soil, and organic compounds transferred by plants can be absorbed and utilized by humans and animals.
The quality of drinking water is closely related to people's health. According to the World Health Organization (WHO) survey, 80% of diseases and 50% of child deaths in the world are related to poor drinking water quality. Using under sink RO system will solve 99% of water quality problems, and dealers should choose a suitable under sink RO system according to the local water quality.
