High filtration accuracy, small pressure difference, large flow, large pollution capacity and long service life. The filter pore diameter is small inside and large outside, with good deep filtration effect. The string wound can withstand high filtration pressure. The wire-wound water filter can effectively remove suspended matter and fine particles in the water. In the production process, no other chemical substances are added, and no other chemical substances are generated, and it can be directly used for the filtration of drinking water and other liquids
