Constructed from acetate cotton wound over a polypropylene plastic core, this filter provides a 20 micron nominal rating, capturing sediment, dirt, rust, and scale particles at a size effective for general-purpose pre-filtration. The cartridge measures 20 inches in length with a 2.5 inch outside diameter, fitting standard 20-inch Big Blue or equivalent filter housings. It is rated for use up to 120 degrees F and weighs 5.9 pounds. Plumbers and water treatment technicians install this cartridge as part of whole-house or point-of-entry filtration systems.\u003c\/p\u003e\n\u003cp\u003eThis filter cartridge is suited for whole-house sediment filtration, well water pre-treatment, irrigation system protection, and pre-filtration ahead of water softeners or reverse osmosis systems. The 20 micron rating targets larger particulate loads common in municipal and well water supplies. Its string-wound construction allows progressive depth filtration, meaning the outer layers capture coarse particles while inner layers capture finer sediment, extending service life in high-sediment applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20 micron nominal rating for general-purpose sediment reduction\u003c\/li\u003e\n  \u003cli\u003eString-wound acetate cotton construction for progressive depth filtration\u003c\/li\u003e\n  \u003cli\u003ePolypropylene plastic core resists corrosion and moisture degradation\u003c\/li\u003e\n  \u003cli\u003e20 inches length with 2.5 inch OD fits standard 20-inch Big Blue filter housings\u003c\/li\u003e\n  \u003cli\u003eMaximum working temperature of 120 degrees F\u003c\/li\u003e\n  \u003cli\u003eSold individually, no multi-pack assembly required\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 Big Blue and equivalent large-diameter filter housings requiring a 2.5 inch outside diameter string-wound cartridge.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or qualified water treatment technician.
