Built from FDA-grade polyester with a polypropylene plastic core, this filter measures 2.5 inches in outside diameter and 20 inches in length, providing a substantial filtration area. The 5 micron rating captures fine sediment, sand, rust, and other suspended solids from potable and process water lines. It is rated for use at temperatures up to 120 degrees F, making it suitable for cold and cool water service. Plumbers and water treatment technicians install this filter in standard 20-inch big-blue or slim-line filter housings.\u003c\/p\u003e\u003cp\u003eThe S23R20A is well suited for residential and light commercial water treatment systems where consistent sediment reduction is required ahead of softeners, RO membranes, or point-of-use fixtures. String-wound construction provides graduated density filtration, capturing larger particles at the outer layers and progressively finer particles toward the core, which extends service life and helps maintain flow rates. Common installation scenarios include well water prefiltration, irrigation line protection, and commercial food-service water prep lines where FDA-grade materials are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5 micron rating removes fine sediment, rust, and suspended solids\u003c\/li\u003e\n\u003cli\u003eString-wound polyester construction provides graduated-density filtration for extended filter life\u003c\/li\u003e\n\u003cli\u003eFDA-grade materials suitable for potable water and food-service applications\u003c\/li\u003e\n\u003cli\u003ePolypropylene plastic core resists corrosion and maintains structural integrity under flow pressure\u003c\/li\u003e\n\u003cli\u003eMaximum working temperature of 120 degrees F suitable for cold and cool water service\u003c\/li\u003e\n\u003cli\u003e20-inch length fits standard big-blue and slim-line 20-inch filter housings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement cartridge for standard 2.5-inch outside diameter, 20-inch plumbing filter housings used in residential and commercial water treatment systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or qualified water treatment technician. Shut off the supply valve and relieve system pressure completely before opening the filter housing.
