Description
Overview
The Unicel C-5601 is a pleated polyester cartridge filter element engineered for residential spa and small-pool applications, delivering 25.0 sq ft of effective filtration area through a Reemay nonwoven polyester media pack on an ABS injection-molded end cap configuration. Nominal filtration efficiency is rated at 15 microns under standard test conditions. The element is constructed with a closed-bottom, open-top end cap geometry seated on a rigid central core for axial stability under spa-circulation pressure loads (typical 5–15 PSI operating range). Maximum continuous service temperature is rated to 104°F for pool applications and 115°F for spa-rated service. UV-stabilized adhesive bond and chemical-resistant polyester fabric provide consistent performance across standard sanitization chemistries.
Service interval recommendation: rinse with fresh water every 2–4 weeks under continuous spa use; chemical soak with dilute TSP or commercial enzyme cleaner every 4–6 weeks to remove accumulated body oils, lotions, and surfactants that resist water rinsing. Replacement is recommended at 12-month intervals for residential spa service or upon ΔP rise of ≥ 5 PSI above clean-filter operating baseline, whichever occurs first. Chemical compatibility: polyester media tolerates continuous service at ≤ 10 ppm free available chlorine or ≤ 30 ppm total bromine; muriatic acid soak at 1:20 dilution (20-minute maximum exposure) is compatible for calcium scale removal, followed by thorough fresh-water rinse prior to reinstallation. Enzyme cleaners compatible without restriction. Standard Unicel 90-day manufacturing defect warranty applies through authorized distribution.
