{"product_id":"unicel-c-7698","title":"Unicel C-7698 Replacement Filter for Hayward CX1000RE | 100 Sq. Ft.","description":"\u003cdiv class=\"pz-pdp\"\u003e\n\u003ch3\u003eOverview\u003c\/h3\u003e\n\u003cp\u003eThe Unicel C-7698 is a pleated polyester cartridge filter element engineered for medium-capacity residential and light commercial cartridge filter housings, delivering 100 sq ft of filtration area through a high-pleat-count Reemay nonwoven polyester media pack. Dimensional specifications: 7.0-inch OD, 3.0-inch ID, 19.4375-inch length, with ABS injection-molded end caps configured open-top\/closed-bottom for standard top-load housing seating. Core construction is rigid PVC for axial stability under sustained operating pressure, and the media is rated to a nominal 20-micron filtration threshold. Continuous service temperature is rated to 104°F at operating pressures up to 25 PSI, with end cap adhesive UV-stabilized for resistance to pool chemistry degradation across standard sanitizer concentrations.\u003c\/p\u003e\n\u003cp\u003eService interval recommendation: residential applications — pressure-differential replacement trigger at ΔP ≥ 8–10 PSI above clean-filter operating baseline, or annual calendar replacement, whichever occurs first. Rinse cycle every 4–6 weeks; chemical soak with TSP solution or enzyme cleaner every 3–6 months to address oils, surfactants, and organic loading that resist standard rinsing. For calcium scale accumulation, the element is compatible with muriatic acid soak at 1:20 dilution (20-minute maximum exposure); rinse thoroughly with fresh water before reinstallation and verify post-installation clean operating pressure. Chemical compatibility: continuous service at ≤ 10 ppm free available chlorine or equivalent bromine concentration; enzyme cleaners compatible without restriction. ABS end cap construction tolerates standard acid wash procedures. Standard Unicel 90-day manufacturing defect warranty applies through authorized distribution.\u003c\/p\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cp\u003eYour order includes the selected quantity of replacement pool filter cartridges.
