{"product_id":"unicel-c-8326","title":"Unicel C-8326 Replacement Filter for Sundance Spas 6473-168 | 125 Sq. Ft.","description":"\u003cdiv class=\"pz-pdp\"\u003e\n\u003ch3\u003eOverview\u003c\/h3\u003e\n\u003cp\u003eThe Unicel C-8326 is a pleated polyester spa cartridge filter element providing 125 sq ft of effective filtration area, engineered for high-capacity Sundance Spas circulation systems. The element is constructed with Reemay-grade nonwoven polyester media in a high-pleat-count configuration, mated to injection-molded ABS end caps for chemical and thermal stability under continuous spa-duty service. Nominal filtration efficiency is rated at 15 microns under standard test conditions. The cartridge is constructed on a structural inner core sized for direct standpipe seating in OEM Sundance manifolds, with end cap geometry held to ±0.030 inch tolerance for bypass-free fitment. Maximum rated continuous service temperature is 104°F, with intermittent excursions to 120°F acceptable per spa-rated element protocol. The 125 sq ft media pack supports extended service intervals relative to lower-area cartridges by distributing particulate load across greater surface area, reducing ΔP rise rate under typical bather loading.\u003c\/p\u003e\n\u003cp\u003eService interval recommendation: rinse with fresh water every 2–4 weeks to remove surface particulate; chemical soak in dilute TSP or commercial enzyme\/cartridge cleaner every 4–6 weeks to address oils, lotions, and surfactant residue resistant to mechanical rinsing. Replace the element at ΔP ≥ 5 PSI above clean operating baseline, or on a 12–15 month calendar cycle under typical residential spa loading — whichever occurs first. Heavy-use or commercial-spa applications warrant accelerated replacement at 6–9 month intervals. Chemical compatibility: continuous service at ≤ 10 ppm free available chlorine or ≤ 30 ppm total bromine; muriatic acid soak at 1:20 dilution compatible for calcium scale removal (20-minute maximum exposure, thorough rinse before reinstallation). Enzyme cleaners compatible without restriction. 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 spa filter cartridges.
