As we all know, the filter element is the core part of the Commercial Water Dispenser. At present, in the more common reverse osmosis water purifiers on the market, the number of filter elements is usually 3 to 6. Many consumers often have the misunderstanding that "the more filter elements, the cleaner the filter elements" when purchasing. But, the more filtering elements, the better?
Generally speaking, the three filter elements of household reverse osmosis water purifiers from water dispenser suppliers are: cotton cloth, activated carbon, and reverse osmosis membrane. Among them, pp cotton, as the first step of water purification, can be the first to intercept large particles such as rust, sediment, and algae in the water. After filtering with pp cotton, the second step is activated carbon adsorption, which can remove residual chlorine and other disinfection by-products and other odors in the water. The second type is reverse osmosis membrane, which is also a reverse osmosis membrane with high filtration accuracy. The nano-pore size can filter out harmful substances, such as heavy metal ions, bacteria, viruses, etc. After these three levels of the gradual water purification process, the water in our home can reach the standard for direct drinking.
Among these three kinds of filter elements, RO membrane is a necessary filter element for the manufacture of direct drinking water. Although water filtered by pp cotton and activated carbon cannot be used directly for drinking, it can play an important role in protecting the RO membrane, thereby prolonging the service life of the RO membrane. However, if you blindly add a filter element with materials and functions similar to pp cotton and activated carbon, it will not only affect the water flow rate and occupy more space, but also increase the user's cost of replacing the filter element in the later stage. Therefore, household reverse osmosis water purifiers do not have as many filter elements as possible. The focus is on filter materials and water purification effects.
In fact, in the high-end products of Commercial Water Dispenser, it has become a trend to focus on the materials and technology of filter elements and reduce the number of filter elements.
To choose a good Commercial Water Dispenser, in addition to considering your own needs, you should also understand the quality of the water purifier brand. Only in this way can we choose a water purifier product that suits us. The more filter elements in the water purifier, the better, please remember.
