Performance centers on an ultra-long rated life and improved dirt adhesion area that reduces clogging, while the twist-and-lock design makes swaps fast and tool-free.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUltra-long service life:\u003c\/strong\u003e Rated up to three years or 24,000 gallons with municipal water, the filter is built for low-maintenance operation and infrequent replacement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertified reduction:\u003c\/strong\u003e Tested against NSF\/ANSI 42 and 53 standards, the cartridge reduces chlorine, taste and odor, lead, and various VOCs for noticeably cleaner water.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePFAS removal:\u003c\/strong\u003e The cartridge targets PFAS including PFOA and PFOS, offering additional protection against these persistent contaminants.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnti-clog design:\u003c\/strong\u003e An upgraded filtration area provides about 20X the dirt adhesion area to improve flow and reduce the chance of premature clogging.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafe materials:\u003c\/strong\u003e Housing and internals use BPA-free, lead-free materials with activated carbon made from coconut shell for effective adsorption.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuick replacement:\u003c\/strong\u003e Twist-and-lock connection lets users swap the cartridge in seconds without tools, simplifying routine maintenance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe RF17 cartridge suits households already using the compatible 17UA or 17UB undersink systems that want long-lasting filtration and reliable reduction of chlorine, lead and PFAS.
