Product Description
The iSpring F3WGB31BPF 3-stage filter replacement pack is designed to keep your WGB31B-PF whole house water filter performing at its best. This 3-stage replacement set features a high-capacity sediment filter (FP15B) to capture dirt, sand, and rust; a carbon block filter (FC15B) to reduce chlorine, taste, odor, and VOCs; and an upgraded carbon filter (FC15B-PF) engineered to remove up to 99% of PFAS (“forever chemicals”) such as PFOA and PFOS commonly found in municipal and well water. Perfect for households using the iSpring WGB31B-PF or other standard 10” x 4.5” whole house water filters, these cartridges provide dependable protection for both city and well water applications. Together, they can filter up to 50,000 gallons of water or last up to 12 months, depending on water quality and usage, ensuring clean, fresh water for every tap in your home. This whole house water filter replacement retains healthy minerals in your water and does not reduce TDS. For total dissolved solids (TDS) reduction, pair it with an iSpring Reverse Osmosis system for complete purification.
