The set combines a sediment stage, a granular activated carbon with KDF stage, and a coconut shell carbon block stage to address chlorine, heavy metals, chloramine, PFAS and visible sediment. Installation and replacements are straightforward for a handy homeowner, and the high flow capability keeps water pressure strong for most homes.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComprehensive filtration:\u003c\/strong\u003e The compound FG25-KS cartridge targets lead, PFAS, heavy metals and other chemicals to protect health and appliances for up to 50,000 gallons.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-stage performance:\u003c\/strong\u003e A polypropylene sediment stage captures particles down to 5 microns while a coconut shell carbon block reduces up to 99% of chlorine for better taste and odor.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThird-party tested:\u003c\/strong\u003e Each carbon block and relevant cartridges are independently tested to meet NSF\/ANSI standards for confidence in contaminant reduction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh flow rate:\u003c\/strong\u003e Designed to support up to 12 GPM, the filters maintain household water pressure so showers and faucets run normally.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEasy maintenance:\u003c\/strong\u003e Cartridges are individually wrapped for freshness and are straightforward to replace using the manual or video guidance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis filter set suits homeowners with municipal or well water who want to reduce chlorine smell and taste, remove heavy metals, and capture visible sediment across the whole house.
