Built from polypropylene cotton wound over a polypropylene plastic core, it measures 2.5 inches in outside diameter and 20 inches in length. The 50-micron rating targets coarse sediment such as sand, silt, and rust particles. FDA-grade materials make it suitable for potable water applications. Licensed plumbers and water treatment technicians are the primary installers, though knowledgeable service pros working on whole-house or point-of-entry filter housings regularly handle this cartridge.\u003c\/p\u003e\u003cp\u003eThis filter cartridge fits standard filter housings that accept a 2.5-inch OD, 20-inch string-wound element. It is commonly installed in whole-house sediment pre-filtration systems, well-water treatment setups, and irrigation pre-filters where coarse particle loads are a concern. The polypropylene cotton string-wound construction provides graduated density filtration, helping extend the life of downstream finer-rated filter stages. Maximum operating temperature is 120 degrees F, making it appropriate for cold and cool water lines but not hot water supply lines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e50-micron string-wound filtration targets coarse sediment including sand, silt, and rust\u003c\/li\u003e\n\u003cli\u003ePolypropylene cotton wound construction provides graduated density for efficient particle capture\u003c\/li\u003e\n\u003cli\u003ePolypropylene plastic core resists corrosion and moisture degradation\u003c\/li\u003e\n\u003cli\u003eFDA-grade materials rated for potable water service\u003c\/li\u003e\n\u003cli\u003eRated to 120 degrees F maximum working temperature\u003c\/li\u003e\n\u003cli\u003eStandard 2.5-inch OD fits widely used residential and light commercial filter housings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement string-wound cartridge filter for standard housings accepting a 2.5-inch OD, 20-inch length polypropylene sediment cartridge element.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and replacement should be performed by a licensed plumber or qualified water treatment technician in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure before opening the filter housing. Inspect housing O-rings for wear when changing cartridges, and do not exceed the rated 120 degrees F operating temperature on the supply line. Dispose of spent cartridges per local waste regulations, as they may contain captured contaminants.\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: 50 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: 20 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polypropylene Cotton\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore Material\u003c\/strong\u003e: Polypropylene Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: FDA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 120 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.2 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: M11R20A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542104015154,"sku":"M11R20A","price":23.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fbf0e6aa03644fd0fa111e19861767dc.jpg?v=1785892159","url":"https:\/\/voomisupply.com\/products\/parker-m11r20a-string-wound-cartridge-filter-50-micron","provider":"Voomi Supply","version":"1.0","type":"link"}
