About This

• GAC/KDF55 Whole House Filtration – Built with granular activated carbon and KDF55 media, the KDF1-4510 helps improve water clarity, taste, and odor in compatible 4.5" x 10" whole house systems. GAC helps reduce chlorine taste and odor, VOCs, bad taste, and unpleasant smells, while KDF55 helps reduce certain heavy metals, supports longer carbon life, and helps inhibit microorganism growth inside the filter.
• KDF55 Heavy Metal Reduction – KDF55 media helps reduce certain heavy metals and common water quality concerns while also helping inhibit microorganism growth inside the filter. The KDF55 and GAC media combination supports longer carbon life and dependable filtration performance in demanding whole house applications.
• Compatible 4.5 x 10 Big Blue Filter – Fits standard 4.5" x 10" Big Blue-style whole house filter housings and is compatible with iFilters MWH-D-WELL systems. Also compatible with GE FXHTC, GXWH40L, GXWH35F, GNWH38S, Culligan RFC-BBSA, WRC25HD, PP10BB-CC, Pentek RFC-BB, and other standard 10" x 4.5" whole house filter cartridges.
• 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 chlorine level, sediment level, iron level, heavy metal concentration, water pressure, and household consumption.
• NSF Certified Materials – Made with NSF certified materials, coconut shell granular activated carbon, and KDF55 media for dependable filtration quality and material safety. Built for residential, rural, light commercial, city water, and well water applications where taste, odor, sediment, and heavy metal reduction matter.
• Important TDS Notice – This GAC/KDF whole house filter is designed to help reduce chlorine taste and odor, VOCs, certain heavy metals, rust, sediment, dirt, sand, silt, bad taste, and odor, but it does not reduce total dissolved solids. TDS reduction typically requires reverse osmosis filtration.
