We all know that the core component of the water purifier is the Water Filter Cartridges(KOKOELECTRIC) https://www.kokoelectric.com/product/water-filter-cartridges/ . The quality of the water filter cartridges directly affects the clean water effect of the water purifier. The water filter cartridges with inferior quality is still rich in more impurities and even carries a peculiar smell. The water flowing out does not conform to the standard and is not beneficial to the human body. For many first-time buyers of water purifiers, they often complain about the poor quality of the water purifiers. For example, the taste of any water is the same as that of the original water purifier, and it also leaks water and costs water. In fact, in the end, it is all the water filter cartridges that has gone wrong. At present, the water filter cartridges of mainstream water purification machines on the market are all composed of activated carbon and hollow membranes. Although activated carbon has a strong adsorption effect, it is easy to reproduce bacteria and needs regular replacement. The hollow membranes are mainly divided into reverse osmosis membranes and ultrafiltration membranes. Experts suggest that for most urban households that use municipal tap water, it is best to buy a clean water machine with ultrafiltration membrane filter element, because the factory water quality meets drinking standards, and the pH value, dissolved oxygen and physiological functions of the water meet certain standards. When the tap water leaves the factory, there are certain parameters. However, secondary pollution is formed during the transportation of the pipe network and storage of secondary water supply equipment, resulting in the tap water in residents' homes being unsafe and undrinkable. The main function of the clean water machine is to deal with the secondary pollution of tap water. The clean water filtered by the ultrafiltration membrane removes impurities and bacteria in the water while retaining trace mineral elements in the water that are beneficial to the human body. Drinking such clean water is most beneficial to the human body. However, no matter what kind of water purifier is used, the quality of the water filter cartridges is the most important, and the cleaning and replacement of it cannot be ignored. Before choosing a water purifier, one must pay special attention to the quality of the water filter cartridges, and then regularly clean and replace the water filter cartridges according to its own water quality. If the quality of the water filter cartridges is excellent, but if the water filter cartridges is not well cleaned and replaced, the service life of the water purifier will not be long either.
