Measuring 30 inches in length with a 2.5-inch outside diameter, this filter delivers 1-micron particulate removal — effective for sediment, dirt, rust, and fine debris in supply lines and treatment systems. The string-wound construction provides depth filtration, trapping particles throughout the media rather than just at the surface. The polypropylene cotton material and polypropylene plastic core meet FDA material grade standards, making this filter suitable for potable water and food-service adjacent applications. Licensed plumbers and water treatment technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis filter is suited for residential and light commercial plumbing systems where fine sediment control is required upstream of water heaters, softeners, reverse osmosis units, or point-of-use fixtures. The 1-micron rating makes it appropriate as a final-stage sediment filter or pre-filter ahead of membrane-based treatment systems. Its 30-inch length fits standard big-blue and comparable filter housings rated for that cartridge size. Maximum working temperature is 120 degrees F, which limits use to cold and warm water lines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-micron filtration rating captures fine sediment, rust, and particulates\u003c\/li\u003e\n\u003cli\u003eString-wound depth filtration design traps particles throughout the media body\u003c\/li\u003e\n\u003cli\u003ePolypropylene cotton media and polypropylene plastic core — FDA material grade\u003c\/li\u003e\n\u003cli\u003e30-inch length with 2.5-inch outside diameter for compatibility with standard large-format filter housings\u003c\/li\u003e\n\u003cli\u003eRated to 120 degrees F maximum working temperature\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a drop-in replacement cartridge for standard large-format string-wound filter housings that accept a 2.5-inch OD by 30-inch cartridge.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a licensed plumber or qualified water treatment technician. Shut off the water supply and relieve system pressure fully before opening the filter housing. Inspect the housing O-ring and replace it if worn before reinstalling the housing cap.
