Built from rayon wound over a polypropylene plastic core, it delivers a 10 micron nominal filtration rating suitable for removing sediment, dirt, and particulate from water lines. The cartridge measures 2.5 inches in outside diameter and 20 inches in length, fitting standard big-blue and comparable filter housings. It carries an FDA material grade designation, making it appropriate for potable water systems. Plumbers and water treatment technicians install this cartridge as part of point-of-entry or point-of-use filtration assemblies in residential and light commercial systems.\u003c\/p\u003e\u003cp\u003eThe E19R20A suits residential and light commercial plumbing systems where sediment reduction is required upstream of fixtures, water heaters, or softeners. Its string-wound construction creates a gradient density that traps larger particles at the outer wrap and finer particles closer to the core, extending service intervals versus surface-type filters. Systems with well water, municipal supply with sediment carryover, or pre-filtration ahead of reverse osmosis units are common installation scenarios for this cartridge.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e10 micron nominal filtration rating for effective sediment removal\u003c\/li\u003e\n\u003cli\u003eRayon string-wound construction over a polypropylene plastic core\u003c\/li\u003e\n\u003cli\u003eFDA-grade materials suitable for potable water contact\u003c\/li\u003e\n\u003cli\u003e2.5 inch outside diameter, 20 inch length fits standard filter housings\u003c\/li\u003e\n\u003cli\u003eMaximum working temperature of 120 degrees F\u003c\/li\u003e\n\u003cli\u003eGradient density winding extends cartridge service life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement cartridge for standard plumbing filter housings that accept 2.5 inch OD by 20 inch string-wound cartridges.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed plumber or qualified water treatment technician should perform cartridge replacement in accordance with local plumbing codes and the housing manufacturer instructions.
