Safety Material: Food grade 100% Polypropylene material, Lead and BPA-Free. Non-toxic, odorless, no leaching or secondary pollution. Providing a healthy, safe water-filtering experience. Authorized Certification: Tested and certified by NSF International against NSF/ANSI Standard 42 for material requirements. Outstanding Advantages: Compared to melt blown filter cartridge, string filter is best choice to filter water with lots of sediment. *Flow Rate: String Wound Filter > Melt-Blow Filter *Dirty-holding Capacity: String Wound Filter > Melt-Blow Filter *Service Life: String Wound Filter > Melt-Blow Filter Standard Universal Size: 10 x 2.5-inch universal filter cartridge size, fits most 10-inch filter housings. Used as a prefilter for reverse osmosis (RO) and whole house water filtration systems, and various commercial and industrial applications. Protect Water Equipment: This filter removes up to 99% of sediment, including rusts, silt, sand, and other undissolved particulates from feedwater. As the first-stage filter in the whole house filtration system, it protects your post-filters, water appliances, pipes, bathroom, and kitchen faucets and shower fittings from clogging, providing a healthier filtered water supply for your home. Long-Life Filter: Our high dirt-loading capacity sediment filters can last up to 20,000 gallons. The filtered capacity and change-out cycle depends on the inlet water quality. Replace the filter at least every six months to maintain performance. Higher Dirt-Holding Capacity: The string wound filter has a deep graded honeycomb structure, dense near the inside core and more open and sparse near the outside edge, forming an effective depth filtration filter, catching larger particulates first and then smaller near the center core, effectively increasing the dirt holding capacity of the filter.Compatible Brands or Models: American Plumber W50PE Ametek R50 APEC Water ESSENCE ROES-50, ROES-75, ROES-PH75, ROES-PHUV75, ROES-UV75-SS, ROES-UV75, FILTER-MAX-ES50, FILTER-MAX-ESPH, RO-45, RO-90, RO-PERM, RO-PUMP, WFS-1000 Aquaboon AB-1C5M, AB-1PL1M, AB-1PL5M, AB-1S1M, AB-1S5M, AB-1SGR1M, AB-1SGR5M, AB-1SW1M, AB-1SW5M Aquacrest AQU-WF96 Aqualink CTO10, PP10 Aquapure AP110 Culligan CW-F, HF-150A, HF-160, HF-360, SCWH-5 Dupont WFPFC3002, WFPFC9001, SCWH-5 Everpure DEV9109, EV910010, EV910853 Express Water RO5DX, ROALK5D, ROUV10DCG, ROALKUV10M, RODI10D, ROELITE9, FLTSETS6C6G6I3M502 FreshWaterSystems PS-27097-50 GE FX12M, FX12P, GXRM10RBL, GXRM10G GeekPure RO5-AF, RO5-UV, RO5-PLUS Global Water RO-505 Harmsco 701-50, 801-20W, 801-50, 801-50W, WB-50W Hydronix CB-25-1001, HX-CB-25-1010, HX-SGC-25-1005, SDC-25-1005, SDC-25-1020, SGC-25-1005, SPC-25-1005, SPC-25-1010, SPC-25-1030, SPC-25-1050, SWC-25-1001, SWC-25-1005, SWC-25-1010, SWC-25-1050 Icepure CTO10, PP10, PPL10, PPW10 iSpring F9K, RCC7AK, RCC7P-AK, RCC7PAK, RCC7, RCS5T, US31, RCC7P, F7-GAC, F7RO, F3_SML , RCC7AK-UV, RCC7D, RCC7U, RCC100P, RCC1UP Max Water 10 inch system, 104001, 104002, 104066 Membrane Solutions CTO-F10-5, GAC-F10, GPP-F10, MPP-F10, PE-F10 Neo-Pure PS-27097-50 Pentair Pentek C1, CBC-10, ECP1-10, ECP5-10, EP-10, EPM-10, OT32, P5, U25 PureDrop RTW5 Pureplus CTO10, PP10, PPL10, PPW10 SimPure CTO-F10-5, DB1025, T1, T2 SpiroPure SP-P5, SP-R550 US Filter R50 Watts Premier WP500032, WP560032, WP560038 Whirlpool WHKF-GD05, WHKF-WHPL, WHKF-WHSW, WHKF-WHWC, WHKF-DWHV *The list is under continuous updating.

Package Includes: For example, if you choose «5 Micron» (Micron Rating) and «6» (Filter Quantity), you will get 6 pieces of 5 Micron 10″x2.5″ water filter. QA: Q:What is a micron rating? A: The unwanted particles found in water are measured in microns. For example, a filter with a micron rating of 5 will filter out contaminants of 5 micron or larger. Our filter with 99% efficiency rating removes 99% of the particles at all above the 5 micron size. Q: How to choose the right size? A: If you choose the right size for your housing, there are not great influence on the flow rate when you replace them. The size is small: there is a significant drop in flow rate. The size is large: there is still some sediment in your water. Please make sure the size is meet your need before ordering.
