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.Multiple Advantages:It has the advantages of high filtration accuracy, flow rate, small pressure difference, high compressive strength, pollution tolerance, non-toxic and tasteless, and no secondary pollution.Maximum Operating Temperature(Celsius): 80 CelsiusApplicable pH value: 1-13Maximum Operating Differential Pressure(Bar): 4.2BarRecommended Changed-out Differential Pressure(Bar): 2.4BarPure Polypropylene MicrofibersString wound filter is a kind of water filter.The textile fiber line which made from specific technology of precision, winding in the porous skeleton (polypropylene) , with thin dense honeycomb structure, can effectively remove the suspended solids in the fluid, particles, rust and other sundry, has the very good filtering characteristics.Multiple advantagesHigh filtration accuracy, small pressure difference, flow, pollution capacity and long service life.The filter pore diameter is small inside and outside, with good deep filtration effect.wound can withstand high filtration pressure.The wire-wound water filter can effectively remove suspended matter and particles in the water.High capacityThe 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.colour:whiteMaterial:Polypropylenesize:Length: 250mmAperture: 10mOuter diameter: 60mmPackage Contents:5 * Water purifier filterOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
