{"product_id":"unicel-c-8419","title":"Unicel C-8419 Replacement Filter for Waterway 817-0200P | 200 Sq. Ft.","description":"\u003cdiv class=\"pz-pdp\"\u003e\n\u003ch3\u003eOverview\u003c\/h3\u003e\n\u003cp\u003eThe Unicel C-8419 is a high-capacity pleated polyester cartridge filter element engineered for residential and light commercial pool applications, delivering 200 sq ft of filtration area in a single-element configuration. Constructed with Reemay nonwoven polyester media at a nominal 20-micron filtration efficiency, the C-8419 features molded ABS end caps with a closed-bottom, open-flow top geometry seated on a reinforced PVC center core for axial rigidity under sustained operating loads. The element is rated for continuous service to 104°F at operating pressures up to 25 PSI, with end cap adhesive bonded to UV-stabilized specifications for resistance to chemical degradation under standard pool water chemistry. High pleat density maximizes media surface area per element length, extending service cycles and reducing ΔP rise rates relative to lower-area cartridges in equivalently sized housings.\u003c\/p\u003e\n\u003cp\u003eService interval recommendation: residential applications — rinse at 4–6 week intervals or upon ΔP rise of 8–10 PSI above clean-filter operating baseline; chemical soak with TSP or commercial enzyme cleaner every 3–6 months to remove oils, surfactants, and organic loading that resist rinse-only cleaning. Replace annually or upon visual evidence of fabric degradation, pleat collapse, or core crush. Chemical compatibility: polyester media and ABS end caps tolerate continuous service at ≤ 10 ppm free available chlorine and standard bromine sanitization; muriatic acid soak at 1:20 dilution is compatible for calcium scale removal (20-minute maximum exposure, thorough fresh-water rinse before reinstallation). Verify housing O-ring condition and lubricate with silicone-based O-ring lubricant at each service interval; confirm post-installation operating pressure against documented clean baseline. Standard Unicel 90-day manufacturer's 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.
