About This

• Whole House Filtration with Anti-Scale Protection: The iSpring Whole House Water Filter System WGB21B-DS combines powerful filtration with reliable anti scale protection to enhance every drop of water in your home. The 1st-stage CTO carbon block filter (FC15B) reduces chlorine, odors, and cloudiness, while the 2nd-stage anti scale water filter (FWDS80K) prevents calcium and magnesium buildup. Acting as an inline water filter, it keeps your household water clear, fresh, and safe.
• High Capacity & Whole Home Coverage: Designed as a compact yet high-performing whole house water filter system, the WGB21B-DS delivers up to 50,000 gallons of purified water—enough for a family of four for a full year. Its 1" ports provide strong flow with minimal pressure drop. This home water filtration system helps reduce chlorine, odor, and sediment while extending the life of your water softener system and plumbing.
• Durable & Leak-Proof Performance: Built with precision and reliability, the iSpring Whole House Water Filter features a reinforced housing and dual O-ring seals for long-term, leak-proof performance. Each component is engineered for strength and stability, ensuring years of consistent, worry-free operation for your entire home.
• Quick Installation and Easy Maintenance: Pre-assembled on a sturdy mounting bracket, this inline water filter system allows for fast, easy DIY installation. It includes a filter wrench and a pressure release valve for safe, quick maintenance. Follow our detailed manual and YouTube tutorials to install it at your main water line and enjoy clean, filtered water throughout your home.
• Peace-of-Mind Customer Service: Backed by iSpring’s commitment to excellence, this whole house water filter system includes a 30-day money-back guarantee and a 1-year warranty, extendable upon registration. Our Atlanta-based support team provides lifetime technical assistance—ensuring your home water filtration system continues to perform reliably for years to come.
• Retains Essential Minerals: Unlike reverse osmosis systems, this filtration system does not reduce Total Dissolved Solids (TDS), allowing beneficial minerals to remain in your water. If you prefer water with lower TDS levels, explore our iSpring Reverse Osmosis (RO) systems for complete purification.
