The pre-filter sits upstream of the main reverse osmosis membrane and multi-stage filter stack, intercepting sediment and particulates before water reaches the primary filtration layers. This protects the RO membrane and extends its service life. Installation is tool-free and takes under a minute, making it well-suited for routine maintenance by plumbers and knowledgeable homeowners alike.\u003c\/p\u003e\u003cp\u003eThis cartridge is intended for residential drinking water applications where an inline pre-filter stage is required. It fits within the Clarifi Tankless Reverse Osmosis system, which uses high-pressure filtration to reduce 90 or more contaminants from potable water. The pre-filter is part of a broader multi-cartridge service interval that includes the carbon filter and the RO membrane, allowing a technician or homeowner to swap all stages in a single service visit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDesigned as a direct replacement pre-filter stage for the Clarifi Tankless Reverse Osmosis system\u003c\/li\u003e\n\u003cli\u003eUpstream placement protects the RO membrane from sediment and particulate loading\u003c\/li\u003e\n\u003cli\u003eTool-free cartridge swap takes under one minute per filter\u003c\/li\u003e\n\u003cli\u003eCompatible with the two-year filter replacement schedule shared by the carbon and RO membrane cartridges\u003c\/li\u003e\n\u003cli\u003eSupports a filtration system rated to reduce 90 or more drinking water contaminants\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement pre-filter cartridge for the DELTA FAUCET Clarifi Tankless Reverse Osmosis System.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePre-filter cartridge replacement is a low-voltage-free, water-side service task. Shut off the feed water supply valve to the RO system before removing the existing cartridge. Follow the system manufacturer's cartridge replacement sequence to avoid cross-contamination between filter stages. Plumbers or water treatment technicians should verify local plumbing code requirements before servicing any point-of-use drinking water system.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Stage\u003c\/strong\u003e: Pre-filter (sediment\/particulate)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Compatibility\u003c\/strong\u003e: Clarifi Tankless Reverse Osmosis System\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Replacement Interval\u003c\/strong\u003e: Two years\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DELTA FAUCET\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: dwq300350\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELTA FAUCET","offers":[{"title":"Default Title","offer_id":51467708989746,"sku":"DWQ300350","price":97.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313947414.webp?v=1783910954","url":"https:\/\/voomisupply.com\/products\/delta-faucet-dwq300350-ro-pre-filter-cartridge","provider":"Voomi Supply","version":"1.0","type":"link"}
