Comparison between long-acting reverse osmosis membrane filter and Dow filter;
1, the material is good: Angel adopts phenol-free polymer liquid silica gel coating material, which is a baby food-grade material; Dow filter element is made of polyamide (commonly known as nylon) film;
2, the effect is better: the service life is as long as 5 years, and the filtering effect is not attenuated.
The desalination rate of long-acting reverse osmosis membrane 2.0 reaches 94%, while that of Dow filter element is only 86%. 1000L (equivalent to a family of three for one year), the desalination rate of Dow filter element will decrease14%;
The water yield of long-acting reverse osmosis membrane 2.0 is 96L/h, while that of Dow is 91l/h; After passing 1000L (equivalent to the consumption of a family of three for one year), the flux of Dow filter element is obviously attenuated, and it is attenuated by more than 20% at the end of its life. "
At present, most of the traditional reverse osmosis membranes on the market have problems such as short service life and large amount of wastewater. Contaminants are easy to deposit on the membrane surface and block the pore size, so the water flow of the water purifier will become smaller, and the filter element must be replaced after a long time.
The core technology of angel water purifier is long-acting reverse osmosis membrane, which can be said to be an important invention of "standing on the shoulders of predecessors" and won ten innovative patents around the world. Its filtration accuracy can reach 0.000 1 micron, which can keep out most harmful substances and filter out more than 99% viruses and bacteria.
Angel's original spiral structure increased the scouring speed of membrane surface water by 500%, and the pollutants were washed away by high-speed water flow before gaining a foothold, which fundamentally solved the problem of membrane element pollution and blockage. Therefore, the life of this long-acting reverse osmosis membrane is as long as 5 years, and the filtration effect is also stable above 95%. You don't have to change the expensive filter frequently, so you can finally cover your small purse!
In addition, the wastewater ratio of long-acting reverse osmosis membrane is very low, and the water utilization rate reaches 75%, which exceeds the national first-class water efficiency standard by 60%.
