It measures 40 inches in length with a 2.5-inch outside diameter and delivers 5-micron filtration to capture sediment from water supply lines. The thermal-bonded construction integrates the filter media without adhesives or binders, maintaining consistent pore structure throughout the cartridge. Rated for service up to 175 degrees F, this filter is suited for both hot and cold water filtration systems. Licensed plumbers and water treatment technicians install this type of cartridge in standard filter housings as part of whole-house or point-of-entry filtration setups.\u003c\/p\u003e\n\u003cp\u003eThis cartridge filter is intended for residential and light commercial plumbing systems where sediment reduction is required at the point of entry or point of use. It fits into standard 40-inch filter housings and is commonly used upstream of water heaters, softeners, and other treatment equipment to protect downstream components from particulate fouling. The all-polypropylene construction, including the core material, makes it compatible with a wide range of water chemistry conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-micron rating for effective sediment reduction from water supply\u003c\/li\u003e\n  \u003cli\u003eThermal-bonded polypropylene media — no adhesives or binders that can leach into water\u003c\/li\u003e\n  \u003cli\u003eFull polypropylene construction including core for broad chemical compatibility\u003c\/li\u003e\n  \u003cli\u003e40-inch length fits standard big-blue and comparable large-format filter housings\u003c\/li\u003e\n  \u003cli\u003eRated to 175 degrees F for use in both cold and hot water filtration lines\u003c\/li\u003e\n  \u003cli\u003e2.5-inch outside diameter for correct fit in standard housing inner dimensions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement cartridge for standard 40-inch plumbing filter housings used in residential and light commercial point-of-entry sediment filtration systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines.
