iSpring FP25B High Capacity 20” x 4.5” Water Filter Replacement Cartridge - Fine Sediment Filter - 5 Micron - Fits Standard 20” x 4.5” Whole House Water Filtration Systems - Pack of 1 (FP25B)
  • Protect Your Family and Household Appliance from Sediments: The FP25B sediment filters are specially designed to remove sediments, dust, sand, large particles, silt, dirt, and rust from water. They are usually used as the first stage of a water filtration system to prevent the filters that follow from getting clogged too soon.
  • Standard Size: Our filter fits standard 20” x 4.5” housings, including brand name models.
  • Top-Notch Quality: The FP25B high capacity polypropylene sediment filter is able to achieve filtration down to 5 microns. The filters are tested by an independent third-party to meet NSF/ANSI standards. They have a capacity of 100,000 gallons of water, enough to supply a family of four with clean water for a full year (depending on your water quality). The 20” x 4.5” filter cartridges have a minimum impact on water flow (up to 15 GPM) and require minimum maintenance.
