The filter element of the water purifier adopts hollow fiber technology. Water enters from the inside of the filter element, under the action of water pressure, the purified water enters through the wall of the filter element. Water that can be drunk directly. Miscellaneous water will be trapped in the pipe wall. When the tap water is turned on without purified water, the water containing impurities will be directly discharged along the water pressure.
China's national industrial standards for water purifiers were promulgated in 2013, including "Special Requirements for the Safety of Ultraviolet Radiation Water Treatment Equipment for Household and Similar Appliances" , the “Safe hot and cold water dispensers for household appliances and similar”. Electrical appliances "Special requirements", "Ultraviolet sterilizers for household water purifiers and the like".
"Reserveirs under pressure for domestic and similar uses of reverse osmosis water purifiers and nanofiltration water purifiers" The drafting meeting of the four national industry standards of domestic water purifiers/water purifiers for water purifiers was held in May 2013. held in Kunming city, Yunnan province, from 17 to 19.
Detailed information:
The function of water purifier water is to remove floating objects, heavy metals, bacteria, viruses, residual chlorine, sediment, rust, microorganisms, etc. -Precision filtration technology, five-stage filtration technology. water purifiers used at home:
The first level is the filter element, also known as PP cotton filter element (PPF). filter at csecond stage granular active carbon (UDF).
The third stage is the precision compressed activated carbon (CTO) filter element.
The fourth stage is the reverse osmosis membrane or ultrafiltration membrane.
The fifth stage is post-activated carbon (small T33). Water purifiers are not only suitable for areas where tap water is seriously polluted, but also can filter residual chlorine in ordinary tap water and improve the taste of water.

The difference between magnetized water and water purifier water:
< p>1. /p>Magnetized water is mainly used in industry and its preparation requires an extremely strong magnetic field and a stable, slow flow of water. Generating a strong magnetic field requires a huge current or a huge permanent magnet, which is definitely not something ordinary peoples can install in their home.
Water purifiers are mainly used in households. They remove floating objects, heavy metals, bacteria, viruses, residual chlorine, sediment, rust, microorganisms, etc. filtered water.
2. Different working principles:
The phenomenon of magnetized water refers to the phenomenon that water containing certain dissolved ferromagnetic minerals flows under a strong magnetic field and exhibits certain magnetic properties.
The water purifier adopts the principle of screen filtering and has a progressive structure. It is composed of multi-stage filter elements connected in series from end to end. The precision of the filter elements is arranged from bottom to top. high to achieve shared interception of impurities by multi-stage filter elements.

Water purification standards:
China's national industrial standard for water purifiers was promulgated in 2013.
Among them , "Special requirements for the safety of ultraviolet radiation water treatment equipment for household appliances and the like", "Special requirements for the safety of hot and cold water dispensers for household appliances and the like", "Requirements special requirements for the safety of hot and cold water dispensers for household and similar appliances", "Special requirements for the safety of hot and cold water dispensers for household and similar appliances", Purification equipment for domestic and similar purposes similar "The drafting work meeting of the four national industry standards of domestic water purifiers and water purifiers was held on May 17, 2013. - Held in Kunming City, China ProvinceYunnan, 19.
Among these four standards, the first two are national standards for water purifiers and are mandatory safety standards; the last two are industry standards and are recommended product standards.
