Independently tested to reduce up to 99% of chlorine while filtering out sediment, rust, odors, bad tastes, herbicides, and other contaminants—helping protect your family, plumbing, and appliances.
• Designed for Simple DIY Installation: The WGB22B whole house water filter system is built for quick and easy setup. Features include detailed YouTube installation guides, a heavy-duty 9” filter wrench, double O-ring seals, standard 1” FNPT connections, and a leak-reducing design for stress-free maintenance.
• Universal 20” x 4.5” Replacement Filters: Unlike whole house water filtering systems that require expensive proprietary cartridges, the iSpring WGB22B uses industry-standard 20" x 4.5" filters that are widely available, easy to replace, and more budget-friendly over time.
• Advanced Multi-Stage Filtration Performance: The first-stage sediment filter captures particles down to 5 microns, while the second-stage CTO carbon block filter uses premium coconut shell carbon. Third-party tested to meet NSF/ANSI standards, the whole home water filter system delivers up to 100,000 gallons of clean filtered water—typically enough for one year of use.
