American Yikou is the inventor of household water softeners and water purifiers. The problem of salt flushing has been solved as early as the invention. Through 92 years of continuous technological innovation, tens of millions of families in different countries around the world are using Yikou water softening equipment in a safe, efficient and energy-saving manner, processed by Yikou water softeners. The salt content of the drinking water is far below the 200 mg/L sodium ion standard set by the Ministry of Health. At the same time, all Yikou water purification equipment holds US NSF, US WQA, EU CE, Canadian CSA, US IS9001, US UL, and China 3C certification. In the United States, the market share of Yikou Water Softener 92 far exceeds that of other brands. At the same time, the Yikou water softener uses Rohm and Haas's special formula resin, which will not be replaced "for life"
The drinking water grade resin produced by Rohm and Haas is called Amberlit SR1L Na. This resin not only passed the inspection of the national quality inspection department, but also obtained the US NSF certification and complies with the US FDA certification standards. The FDA has strict standards for ion exchange resins used in the field of drinking water. This resin can be widely used in bottled water and drinking water softening treatment.
Compared with the resins currently used in the Chinese market, the outstanding feature of Amberlit SR1L Na is that it is more hygienic and safer, because AmberlitSR1L Na does not use any organic solvents such as EDC (ethane dichloride) during the production process. EDC is a toxic carcinogen that is easily volatile and therefore easily breaks off the surface of the resin and enters drinking water. The drinking water resin adopts an EDC-free synthesis process, which fundamentally eliminates the potential harm caused by using EDC as a chemical reaction carrier to produce resin. Consumers do not need to worry about the residual EDC in the drinking water after it has been softened.
The food-grade resin products produced by Rohm and Haas comply with US FDA regulations and European food management regulations.
In addition, Amberlite SR1L Na is currently the only resin on the market that is approved for treating drinking water in the United States, France, Australia, the United Kingdom, Japan and other countries (so, only water from American Yikou water softeners can be Drink with confidence).
Amberlit SR1L Na resin can be regenerated 5,000 times. If we restore and regenerate it every 3 days, it can still be used for 40 years. However, too much impurities and rust in the water will reduce the service life of the resin.
