iSpring WGB32B-MKS 3-Stage Whole House Water Filtration System, Removes Iron, Manganese, Hydrogen Sulfide, Chlorine, and Sediment, 15 GPM Flow, w/ F3WGB32BMKS Replacement Filter Pack

The WGB32B-MKS delivers whole-house water protection with a high-flow 1-inch design supporting up to 15 GPM. Its three-stage filtration reduces iron (up to 3.0 ppm), manganese (up to 1.0 ppm), chlorine, hydrogen sulfide, lead, mercury, and sediments while preserving beneficial minerals. Large 20-inch by 4.5-inch cartridges extend service life, and the system’s straightforward installation and dependable customer support make it a practical, long-term solution for improving household water quality.

• Advanced 3-Stage Filtration: The WGB32B-MKS system employs three precision-engineered filters for comprehensive protection. The FP25B sediment filter captures particles down to 5 microns, the FG25B-KS compound filter targets chlorine, lead, mercury, hydrogen sulfide, and heavy metals, while the FM25B iron filter effectively reduces iron up to 3.0 ppm and manganese up to 1.0 ppm.‌
• High Flow and Long Lifespan: Designed for high-capacity households, this system maintains up to 15 GPM flow with minimal pressure drop. Depending on water quality and usage, each filter set provides a family of four with clean water for up to a year.
• DIY-Friendly Installation: Features 1” NPT inlet/outlet connections and standard 20” x 4.5” filter cartridges for easy setup. Includes a detailed manual and access to iSpring’s instructional YouTube videos for guided installation.
