Wound from polypropylene cotton over a polypropylene plastic core, it delivers 10-micron filtration across a full 20-inch filter length. The FDA-grade materials make it suitable for potable water systems where material compliance matters. Plumbers and water treatment technicians install this filter in standard 2.5-inch OD housing assemblies as part of whole-house or point-of-entry filtration setups. The string-wound construction creates a graded density that traps sediment throughout the depth of the media, extending service life compared to surface-only filters.\u003c\/p\u003e\u003cp\u003eThis filter is suited for residential whole-house filtration, well water sediment pre-treatment, and commercial point-of-entry systems where 10-micron particulate control is required. Its 20-inch length fits big-blue and standard 20-inch filter housings. Typical applications include pre-filtration ahead of water softeners, reverse osmosis systems, and UV disinfection units. Maximum service temperature is rated at 120 degrees F, keeping it appropriate for cold and ambient-temperature water lines rather than hot water service.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e10-micron nominal rating for effective sediment and particulate removal\u003c\/li\u003e\n\u003cli\u003eString-wound polypropylene cotton media with graded-density construction\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\u003e20-inch length fits standard and big-blue 20-inch filter housings\u003c\/li\u003e\n\u003cli\u003e2.5-inch outside diameter for drop-in compatibility with matching housing sizes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for standard 20-inch string-wound cartridge filter housings with a 2.5-inch inside diameter seat.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers or water treatment professionals.
