It measures 2.5 inches in outside diameter and 20 inches in length, with a 50-micron rating that captures sediment, rust, and particulate matter from water supply lines. The core is constructed from polypropylene plastic, and the filter media meets FDA material grade standards. Rated for a maximum working temperature of 120 degrees F, this cartridge suits a range of residential and light commercial inline filtration systems. Licensed plumbers and water treatment technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis cartridge filter is used in standard 20-inch filter housings for point-of-entry and point-of-use plumbing systems. Typical applications include sediment prefiltration for whole-house water treatment systems, irrigation supply lines, and commercial process water lines where coarse particulate removal is required. The 50-micron rating makes it appropriate as a first-stage filter ahead of finer membrane or carbon filtration stages. Its polyester string-wound construction provides consistent depth filtration across the full length of the cartridge.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e50-micron rating for coarse sediment and particulate removal\u003c\/li\u003e\n  \u003cli\u003eString-wound polyester media for depth filtration performance\u003c\/li\u003e\n  \u003cli\u003ePolypropylene plastic core for chemical resistance and structural integrity\u003c\/li\u003e\n  \u003cli\u003eFDA-grade materials suitable for potable water applications\u003c\/li\u003e\n  \u003cli\u003eRated to 120 degrees F maximum working temperature\u003c\/li\u003e\n  \u003cli\u003eStandard 20-inch length fits widely available filter housings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement cartridge for standard 20-inch plumbing filter housings accepting 2.5-inch outside diameter string-wound cartridges.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or qualified water treatment technician.
