Key Features

• 💧 Built For Well Water Problems – Designed for homes dealing with sediment, rust, iron staining, sulfur or rotten egg odor, bad taste, chlorine taste, heavy metals, and unpleasant smells. This 20-inch system helps improve incoming water before it reaches faucets, showers, fixtures, laundry, water heaters, dishwashers, washing machines, and other water-using appliances.
• 💧 Washable Anti-Bacterial Pleated Pre-Filter – The first-stage pleated sediment filter provides a large filtration surface area to help capture dirt, rust, sand, silt, and suspended particles before water reaches the specialty media stage. The pleated design helps maximize dirt-holding capacity, supports strong flow, and is especially useful for well water applications with heavier sediment levels. The anti-bacterial pleats are designed to resist harboring bacterial growth, allowing the filter to be rinsed and reused while helping maintain cleaner filter media between replacements.
• 💧 GAC/KDF Advanced Filtration – The second cartridge combines granular activated carbon and KDF media for two additional filtration stages in one housing. The GAC helps reduce chlorine taste and odor, bad taste, VOCs, and common organic compounds, while KDF media helps reduce iron, sulfur odor, heavy metals, and other well water concerns through redox filtration, resulting in cleaner, clearer, better-tasting water throughout the home.
• 💧 Helps Protect Plumbing & Appliances – By helping reduce sediment, rust, iron, sulfur odor, chlorine taste, odor, heavy metals, and common water-related buildup, the MWH-D20-WELL helps protect plumbing lines, fixtures, valves, water heaters, washing machines, dishwashers, and downstream filtration equipment. Cleaner incoming water helps reduce stress on the systems and appliances your home depends on every day.
• 💧 Commercial Grade 4.5 x 20 Housings – Built with durable 4.5" x 20" whole house filter housings and 1" ports to support strong residential water flow. The heavy-duty Big Blue-style design is made for demanding well water applications where smaller filters may clog quickly, lose flow, or require more frequent replacement.
• 💧 Long-Lasting Filter Performance – Engineered for reliable whole house filtration with up to 100,000 gallons of capacity or 6-12 months of service life, depending on water quality and usage. Actual lifespan may vary based on water pressure, sediment level, iron level, sulfur level, chlorine level, heavy metal concentration, and household consumption. Replace when water flow slows, odor returns, or filtration performance begins to decline.
• 💧 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. Use iFilters SP30-KDF2-4520 replacement filters for proper fit, reliable filtration, and continued system performance.
• 💧 Important TDS Notice – This whole house pleated sediment, GAC, and KDF filtration system is designed to help reduce sediment, rust, iron, sulfur odor, chlorine taste, odor, bad taste, heavy metals, and common well water 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.
