Wound from FDA-grade cotton over a polypropylene core, this filter delivers 20-micron filtration in a standard 2.5-inch OD by 20-inch body. The string-wound construction creates a graduated density from the outer layer to the core, improving dirt-holding capacity compared to uniform-density media. Licensed plumbers and water treatment technicians install this filter in residential and light commercial applications as a sediment pre-filter or point-of-entry stage.\u003c\/p\u003e\n\u003cp\u003eThis filter fits standard 20-inch Big Blue or equivalent filter housings used in whole-house filtration, irrigation pre-filtration, and commercial water conditioning systems. Its 20-micron rating makes it appropriate as a first-stage sediment filter upstream of finer membrane or carbon block stages. The cotton media is rated for service at water temperatures up to 120 degrees F, keeping it within range for cold and warm water supply lines in typical plumbing installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20-micron rating captures sediment, sand, rust, and particulate at an effective removal threshold for pre-filtration stages\u003c\/li\u003e\n  \u003cli\u003eString-wound cotton construction provides graduated density for higher dirt-holding capacity\u003c\/li\u003e\n  \u003cli\u003eFDA-grade cotton media suitable for potable water applications\u003c\/li\u003e\n  \u003cli\u003ePolypropylene core resists moisture and maintains structural integrity under normal water pressure\u003c\/li\u003e\n  \u003cli\u003eRated to 120 degrees F maximum working temperature for cold and warm water supply lines\u003c\/li\u003e\n  \u003cli\u003eStandard 2.5-inch OD and 20-inch length fits widely available filter housings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service cartridge for standard 20-inch Big Blue and equivalent 2.5-inch OD filter housings used in residential and light commercial plumbing filtration systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or qualified water treatment technician in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure before opening the filter housing. Inspect the housing O-ring and replace if cracked or deformed to prevent bypass leakage.
