[Multiple Advantages]:It has the advantages of high filtration accuracy, large rate, small pressure difference, high compressive strength, large pollution tolerance, non- and tasteless, and no secondary pollution. [ Quality Filtration]: wound water filter have a deep bed filtration function,which It presents honeycomb structure of being dense inside and sparse outside. Wound sediment filter can reduce 99.99% sand, scale, rust, sediment, particles. [High Capacity]: The filter can filter 20000 - 30000 gallons depending on water quality. Suggest to replace it every 3- 6 months for the average household for optimal performance depending on the use. [Dimensions]: Universal water filter replacement fits any standard 10 inch RO and Whole House systems. [Excellent performance]: wound filter elements adopt POLYPROPYLENE Microfibers to be tightly wound on the porous framework according to a specific process, The honeycomb structure with sparse outside and dense inside,it has a good deep filtration effect, and can effectively remove suspended solids, rust, particles and other impurities in the liquid
