Product Details

✓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. This filter can also be used for pool and hottub.
✓Standard Size: Our FP25B whole house water filter fits standard housings that require 20” x 4.5” water filters, including brand name models.
✓Top-Notch Quality: The FP25B high capacity polypropylene whole house 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. FP25B water filters 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.
✓Peace of Mind Customer Service: Register online to activate your manufacturer warranty and life-time free tech support from U.S. local support team. We stand behind our products and if you encounter any problems with any of our products please reach out to us immediately. We are happy to help!
✓Please Note: The water filter cartridges are individually wrapped to ensure freshness. Please unwrap the cartridges before use. Unlike an RO membrane, the filters don’t reduce Total Dissolved Solids (TDS), and instead keeps healthy minerals in your water. If you are interested in a filter that removes TDS, consider our iSpring Reverse Osmosis (RO) systems.
