Quality Filtration: The wound water filter features a deep bed filtration function with a honeycomb structure that is dense inside and sparse outside. It can reduce 99.99% of sand, scale, rust, sediment, and particles. High Capacity: The filter can process 20,000 to 30,000 gallons depending on water quality. It is recommended to replace the filter every 3 to 6 months for optimal performance in an average household, depending on usage. Multiple Advantages: Offers high filtration accuracy, high flow rate, low pressure drop, high compressive strength, high dirt-holding capacity, non-toxic and tasteless materials, and no secondary pollution. Maximum Operating Temperature: 80C Applicable pH Range: 113 Maximum Operating Differential Pressure: 4.2 Bar Recommended Replacement Differential Pressure: 2.4 Bar Material: Pure polypropylene microfibers String wound filter is a type of water filter constructed by precision winding textile fiber onto a porous polypropylene core, forming a thin, dense honeycomb structure. It effectively removes suspended solids, particles, rust, and other impurities from water, providing excellent filtration performance. Additional Benefits: High filtration accuracy, low pressure drop, high flow rate, high contaminant capacity, and long service life. The pore size is smaller on the inside and larger on the outside, enabling effective deep filtration. The wound construction withstands high filtration pressures. The filter efficiently removes suspended matter and particles from water.
