About This

• Compatible Replacement Filter Set – The SP30-KDF2-4520 is designed as the OEM replacement filter set for iFilters MWH-D20-WELL whole house filtration systems and other compatible 4.5" x 20" dual filter housings.
• Washable Anti-Bacterial Pleated Pre-Filter – The first-stage pleated sediment filter provides a large filtration surface area to help capture sediment before water reaches the specialty media stage. 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. 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.
• Built For Well Water Problems – Ideal for homes dealing with sediment, rust, iron staining, sulfur or rotten egg odor, chlorine taste, bad taste, and unpleasant smells. This replacement set helps maintain cleaner incoming water before it reaches faucets, showers, laundry, water heaters, dishwashers, washing machines, plumbing, fixtures, and downstream equipment.
• Long-Lasting Filter Performance – Designed for reliable whole house filtration with recommended replacement every 6-12 months, depending on water quality and usage. Actual lifespan may vary based on sediment level, iron level, sulfur level, chlorine level, water pressure, and household consumption. Replace when water flow slows, odor returns, or filtration performance begins to decline.
• Easy Filter Maintenance – Replacing both cartridges together helps keep your MWH-D20-WELL system working as intended. The complete filter set makes maintenance simple by giving you the correct sediment and GAC/KDF replacement cartridges needed to help restore water clarity, taste, odor, and whole house filtration performance.
• Important TDS Notice – This pleated sediment and GAC/KDF replacement filter set is designed to help reduce sediment, rust, iron, sulfur odor, chlorine taste and odor, VOCs, heavy metals, bad taste, and common well water concerns, but it does not reduce total dissolved solids. TDS reduction typically requires reverse osmosis filtration.
• 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.
