Unicel C-4310 Replacement Filter for Waterway 500-0014 | 10 Sq. Ft.

Overview

The Unicel C-4310 is a pleated polyester spa cartridge filter element delivering 10.0 sq ft of effective filtration area in a compact, single-element form factor engineered for residential spa and small water feature circulation systems. Dimensional specifications: 4.9375-inch OD, 2.125-inch ID, 4.5625-inch overall length, with semi-circular SAE handle integrated into the top end cap for tool-free service removal. End cap construction is injection-molded ABS with closed bottom and open-flow top configuration; the media pack is Reemay nonwoven spunbond polyester at a nominal 20-micron filtration efficiency, supported on an axial PVC core for rigidity under standard spa operating pressures (5–15 PSI). The element is rated for continuous service at temperatures up to 104°F, with short-duration excursions to 115°F within manufacturer tolerance.

Service interval recommendation: rinse with fresh water every 2–4 weeks under typical residential bather load; chemical soak in dilute TSP or commercial enzyme cleaner every 4–6 weeks to remove body oils, lotions, and surfactant residue that resist mechanical rinsing. Replacement is recommended at 12–15 month intervals, or earlier when ΔP rises ≥ 5 PSI above the clean-element operating baseline, when visible fabric degradation (channeling, pleat collapse, or tears) is observed, or when chemical cleaning no longer restores baseline flow. Chemical compatibility: polyester media and ABS end caps tolerate continuous operation at ≤ 10 ppm free available chlorine or ≤ 30 ppm total bromine; muriatic acid wash at 1:20 dilution is compatible for calcium scale removal (20-minute maximum exposure, followed by thorough fresh-water rinse). Standard Unicel 90-day manufacturing defect warranty applies through authorized distribution.
