About This

• 2-Stage Whole House Filtration – This 4.5 x 20 system combines string wound sediment filtration with CTO carbon block filtration to help improve water clarity, taste, and odor throughout the home. Stage 1 helps capture dirt, rust, sand, silt, and sediment, while Stage 2 helps reduce chlorine taste and odor, bad taste, and unpleasant smell before water reaches faucets, showers, fixtures, and appliances.
• Designed For City & Well Water – Built for homes dealing with sediment, rust, sand, silt, chlorine taste, bad taste, and unpleasant odor in city or well water supplies. This 20-inch whole house system is a strong filtration option for households that need sediment protection, carbon filtration, and higher-capacity performance in one 2-stage system.
• Helps Protect Plumbing & Appliances – By helping reduce sediment, rust, sand, silt, chlorine taste, and odor, this whole house system helps protect plumbing lines, fixtures, valves, water heaters, washing machines, dishwashers, and downstream equipment from common water-related buildup. It is designed to support cleaner water flow and dependable household water performance.
• Commercial Grade 4.5 x 20 Housings – Built with 4.5" x 20" whole house filter housings and 1" ports to support strong residential flow performance. The heavy-duty Big Blue-style design is made for demanding city and well water applications where smaller filters may not provide enough dirt-holding capacity, chlorine reduction capacity, or service life.
• Long-Lasting Filter Performance – Engineered for reliable whole house filtration with up to 100,000 gallons of capacity or up to 12 months of service life, depending on water quality and usage. Supports up to 15 GPM flow rate for steady household water performance, with actual lifespan and flow varying based on water pressure, sediment level, chlorine level, and household consumption.
• Easy Installation & Replacement Filters – Designed for straightforward installation and routine maintenance with 1" ports, a housing wrench, and pressure relief valves for easier filter changes. The larger 20-inch cartridge format provides extended filter capacity while keeping routine maintenance simple.
• Replacement Filter Compatibility – Designed for use with the iFilters SW-CB5-4520 replacement filter set for OEM fit and reliable, trusted filtration. Using the correct replacement filters helps maintain proper system performance, fit, flow, and filtration results over the life of the system.
• Important TDS Notice – This whole house sediment and carbon block filtration system is designed to help reduce sediment, rust, sand, silt, chlorine taste, odor, bad taste, VOCs, and common water quality concerns, but it does not reduce total dissolved solids. TDS reduction typically requires reverse osmosis filtration and should not be expected from this type of whole house filter system.
• Lifetime Technical Support – Your satisfaction is important to us. Every iFilters filter is backed by knowledgeable USA-based lifetime technical support. Whether you need help confirming compatibility, installing your filter, troubleshooting performance, or choosing the right replacement cartridge, our team is here to help before and after your purchase.
