Product Details
✓[Whole House Water Filter that Protect Your Family and Household Appliance from Sediment, Chlorine, and More] Say goodbye to smelly, bad tasting water! Our F4WGB22B whole house water filters are specially designed to remove up to 99% of chlorine from water as well as sediment, rust, herbicides, industrial solvents, and various other contaminants.
✓[Whole House Filter with Standard Size] Our water filter set fits standard housings that require 20” x 4.5” whole house water filter cartridges, including brand name models. The 20” x 4.5” whole house water filter replacement cartridges have a minimum impact on water flow (up to 15 GPM) and require minimum maintenance.
✓[Top-Notch Whole Home Water Filter] The 1st stage high capacity polypropylene sediment filter achieves filtration down to 5 micron. The 2nd stage carbon block water filters are made of high-quality coconut shell carbon for maximum filtration efficiency and filter life. Both water filters are tested by an independent third-party to meet NSF/ANSI standards. Both water filters have a capacity of 100,000 gal. of water, enough to supply a family of four with clean water for a full year.
✓[Peace of Mind Customer Service] Register online to activate your manufacturer 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 whole house water filter replacement cartridges are individually wrapped to ensure freshness. Please unwrap before use. Unlike an RO membrane, these whole home water filters don’t reduce Total Dissolved Solids (TDS), and instead keep healthy minerals in your water. If you are interested in a filter that removes TDS, consider our iSpring RO systems.
