Quality Filtration: String Wound water filter features a deep bed filtration, providing a honeycomb structure that is dense inside and sparse outside. String Wound sediment filter can reduce 99.99% sand, scale, rust, sediment, particles. High Capacity: The filter can filter 20,000 - 30,000 gallons depending on water quality. Recommended to replace it every 3-6 months for an average household for optimal performance depending on usage. Multiple Advantages: It has the advantages of high filtration accuracy, flow rate, small pressure difference, high pressure resistance, impurity tolerance, non-toxic and tasteless, and no secondary pollution. Maximum operating temperature (Celsius): 80 Celsius Applicable pH value: 1-13 Maximum operating differential pressure (Bar): 4.2 Bar Recommended replacement differential pressure (Bar): 2.4 Bar Clean polypropylene microfiber String Wound filters are a type of water filter. The textile fiber line made with specific precision technology, wound in the porous skeleton (polypropylene), with a thin, dense honeycomb structure, can effectively remove the suspended solids in the liquid, particles, rust and other impurities, has very good filtration properties. Multiple Advantages High filtration accuracy, small pressure difference, flow, impurity capacity and long service life. The filter pore diameter is small inside and outside, with good depth filtration effect. String Wound can withstand high filtration pressure. Thread-wrapped water filter can effectively remove suspended solids and particles in the water. High Capacity The filter can filter 20,000 - 30,000 gallons depending on water quality. Recommended to replace it every 3-6 months for an average household for optimal performance depending on usage.
