Constructed from acetate cotton wound over a tinned steel core, this filter delivers 1 micron filtration across a 20-inch length with a 2.5-inch outside diameter. The string-wound construction provides graduated density filtration, capturing sediment and particulate from the outside of the cartridge inward. It is rated for water temperatures up to 250 degrees F, making it suitable for both cold and hot water service lines. Licensed plumbers and filtration system technicians are the primary installers for this type of cartridge.\u003c\/p\u003e\n\u003cp\u003eThe WC39R20 is suited for residential and light commercial plumbing filtration systems where fine particulate removal is required. Its 1 micron rating makes it appropriate for pre-filtration ahead of sensitive downstream equipment or for point-of-entry sediment reduction. The 20-inch length fits standard big-blue or industry-standard 20-inch filter housings commonly found in whole-house and commercial water treatment installations. The acetate cotton media and tinned steel core provide reliable performance across a wide range of water conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1 micron rating for fine sediment and particulate filtration\u003c\/li\u003e\n  \u003cli\u003eAcetate cotton string-wound media for graduated depth filtration\u003c\/li\u003e\n  \u003cli\u003eTinned steel core for structural integrity and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eRated up to 250 degrees F maximum working temperature\u003c\/li\u003e\n  \u003cli\u003e20-inch length fits standard 20-inch big-blue and compatible filter housings\u003c\/li\u003e\n  \u003cli\u003e2.5-inch outside diameter for proper housing seal and flow distribution\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit cartridge for standard 20-inch plumbing filter housings that accept 2.5-inch outside diameter string-wound cartridges.\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.
