It measures 30 inches in length with a 2.5-inch outside diameter and delivers 1-micron filtration to capture fine sediment, dirt, and particulate from water and compatible process fluids. The filter body is wound from FDA-grade cotton over a stainless steel core, giving it solid structural integrity up to 250 degrees F. Licensed plumbers and industrial maintenance technicians are the primary installers. The stainless steel core prevents collapse under pressure, and the cotton media provides broad chemical compatibility for potable water and light-duty process lines.\u003c\/p\u003e\u003cp\u003eThis filter is suited for residential and light commercial water treatment systems, point-of-entry sediment reduction, and industrial process filtration where sub-micron particulate control is required. The 1-micron rating makes it appropriate for pre-filtration ahead of carbon blocks, RO membranes, or UV disinfection systems. Its 30-inch length fits standard Big Blue or comparable 30-inch filter housings commonly used in high-flow residential and small commercial installations. FDA-grade cotton media makes it acceptable for potable water service.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-micron filtration rating removes fine sediment and particulate from water lines\u003c\/li\u003e\n\u003cli\u003eFDA-grade cotton string-wound construction compatible with potable water systems\u003c\/li\u003e\n\u003cli\u003eStainless steel core resists collapse and maintains filter geometry under pressure\u003c\/li\u003e\n\u003cli\u003eRated to 250 degrees F for use in hot-water and light process fluid applications\u003c\/li\u003e\n\u003cli\u003e30-inch length suits high-flow Big Blue style filter housings\u003c\/li\u003e\n\u003cli\u003eString-wound depth media captures particles throughout the full filter depth, extending service life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service cartridge for standard 30-inch Big Blue and comparable large-format filter housings used in residential and light commercial plumbing filtration systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed plumber. Shut off the water supply and relieve line pressure before opening the filter housing. Inspect the housing o-ring and replace it if cracked or deformed before reinstalling the housing sump. Torque the housing sump to the manufacturer specification printed on the housing body, and restore pressure gradually while checking for leaks.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: String-Wound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMicron Rating\u003c\/strong\u003e: 1 micron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 30 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Media Material\u003c\/strong\u003e: Cotton (FDA Grade)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARKER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 39R30S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540515062066,"sku":"39R30S","price":49.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/714b7c30850e5aa8dd4e4435c4c1bf58_aeb6d75b-1551-48ed-9bee-2639d4206701.jpg?v=1785857137","url":"https:\/\/voomisupply.com\/products\/parker-39r30s-string-wound-cartridge-filter-1-micron","provider":"Voomi Supply","version":"1.0","type":"link"}
