The core uses a 0.01 μm hollow-fiber UF membrane paired with a silver ion membrane and an activated carbon block to target rust, sediment, organic matter, and heavy metals. The fluoride reduction stage employs a dedicated membrane, additional carbon block, and three sediment PP membranes to intercept fluoride and chlorine. These elements are NSF\/ANSI 42 certified for performance reliability.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e8-stage filtration for multi-layer protection\u003c\/li\u003e\n\u003cli\u003e0.01 μm UF membrane for fine particle capture\u003c\/li\u003e\n\u003cli\u003eSilver ion membrane adds a hygienic layer of protection\u003c\/li\u003e\n\u003cli\u003eActivated carbon block reduces tastes and odors\u003c\/li\u003e\n\u003cli\u003eDedicated fluoride reduction stage addresses fluoride and chlorine\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFluoride reduction and materials\u003c\/h3\u003e\n\u003cp\u003eThe fluoride filters use advanced fluoride reduction material rather than standard activated alumina, helping reduce fluoride by up to 90% and meeting lead-free material standards (NSF\/ANSI 372).
