In general, in order to improve the quality of the outflowing water, people will let the tap water flow through a lot of filter cartridge machine. Therefore, when we buy a water purifier, we must first look at the water purifier with several stages of filtration. The primary and secondary water purifiers only have one or two filters, which are basically obsolete products on the market. The filtered water is of poor quality and is best not to be used. If you want to save money, you can consider a water purifier with a three-stage filter cartridge machine; if you pay attention to hygiene, safety and health, a water purifier with a level four or higher is the best choice, because when the tap water is purified by a five-level filter cartridge, The impurities, bacteria, and viruses in the water will be completely removed, and the feeling in the mouth will be very pure and sweet.
If a three-stage or four-stage water filter is PP cotton or hollow fiber in the first filter of the water inlet, it must be replaced after a period of use, because PP cotton and hollow fiber cannot be used. It needs to be changed frequently because it is cleaned, otherwise it will cause blockage of the filter cartridge machine, and the blockage will rot, ferment and odor, making the filtered tap water polluted for a second time.
When we choose a water purifier, it is best to buy high-quality filter cartridge machine, such as precision ceramic filter cartridge machine. In the water purifier, the precision ceramic filter cartridge machine must be used as the first-level filter cartridge machine, so that all impurities and bacteria in the tap water can be blocked on the surface of the ceramic filter. After using it for a period of time, only cleaning is required, Replace it. And the precision of the last filter device at the water outlet must reach 0.01 micron, which can filter bacteria and viruses in the water 100%.
