It features a rayon winding over a polypropylene plastic core, providing 20-micron filtration to remove sediment, dirt, rust, and particulate matter from water lines and process fluid systems. The outer diameter measures 2.5 inches and the filter is 20 inches long, fitting standard sump-style filter housings. Materials meet FDA grade requirements, making it suitable for potable water and food-adjacent applications. Plumbers and water treatment technicians install this cartridge as a point-of-entry or point-of-use pre-filter stage.\u003c\/p\u003e\u003cp\u003eThis filter is used in residential and light commercial plumbing systems where particulate removal is required upstream of appliances, water heaters, or softeners. The string-wound construction provides graduated depth filtration, capturing larger particles at the outer layers and finer particles closer to the core. The 20-micron rating makes it appropriate for general sediment control in municipal and well water supply lines. Maximum working temperature is 120 degrees F, limiting use to cold and warm water service lines rather than high-temperature process applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e20-micron filtration rating for sediment and particulate removal\u003c\/li\u003e\n\u003cli\u003eString-wound rayon construction for graduated depth filtration\u003c\/li\u003e\n\u003cli\u003ePolypropylene plastic core for chemical compatibility and structural support\u003c\/li\u003e\n\u003cli\u003eFDA-grade materials suitable for potable water service\u003c\/li\u003e\n\u003cli\u003e2.5-inch OD fits standard sump-style filter housings accepting 2.5-inch cartridges\u003c\/li\u003e\n\u003cli\u003eRated to 120 degrees F maximum working temperature\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement cartridge for standard sump-style filter housings that accept 2.5-inch OD by 20-inch length string-wound cartridges in plumbing and water treatment systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed plumber or water treatment technician should install this cartridge following local plumbing code requirements. Shut off the water supply and relieve system pressure before opening the filter housing to swap cartridges.
