Each set includes two cartridges made from certified coconut shell carbon with dual O-ring seals to prevent bypass. They are intended for routine replacement after approximately 10,000 gallons under normal usage and are a direct substitute for many FR1 and RCS housings — but they will not replace or fit FRE-10-GN or PRE-10GN-style filters, so check your housing before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these cartridges improve RV tap water taste and clarity?\u003c\/h3\u003e\n\u003cp\u003eThe coconut shell activated carbon media adsorbs chlorine, odors, and organic tastes while trapping visible sediment and rust particles.

FILSADAE KW1-compatible replacement cartridges are aimed at RV owners, campers, and mobile-home residents who use WaterPur RCS or FR1 housings and want an economical, carbon-based option to reduce taste, odor, and visible particulates. If you rely on onboard filtration for drinking or cooking while traveling and need a straightforward, screw-in replacement, this two-pack offers an accessible maintenance solution. Do not buy this set if your system specifies FRE-10-GN or PRE-10GN cartridges — those use different dimensions and will not fit.\u003c\/p\u003e\n\n\u003cp\u003eTechnical features at a glance: certified coconut shell carbon media, dual O-ring seal to prevent bypass, compatibility with KW1 cartridge form, recommended replacement interval (~10,000 gallons), and sold as a set of two replacements. These cartridges focus on improving sensory water quality and removing large particles rather than filtering bacteria or viruses. Always verify your housing model and follow local guidance for potable water safety.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will these fit my WaterPur FR1 housing?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes—these are made to be compatible with WaterPur FR1 and RCS housings that accept KW1 cartridges.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do they filter bacteria or viruses?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No—these carbon cartridges reduce taste, odor, and particles but are not rated for microbiological disinfection.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"FILSADAE","offers":[{"title":"Default Title","offer_id":48086483828894,"sku":"B0DY16B9BB","price":44.96,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/filsadae-front-packaging-rv-filter.jpg?v=1785899191","url":"https:\/\/northtrailauto.ca\/products\/filsadae-rv-water-filter-replacement-kw1-style-cartridges-set-of-2-coconut-shell-carbon-dual-o-ring-seal","provider":"North Trail Auto","version":"1.0","type":"link"}
