Unicel C-9499 Replacement Filter for Hayward CX1250RE | 120 Sq. Ft.

Overview

The Unicel C-9499 is a pleated polyester cartridge filter element engineered for residential and light commercial swimming pool applications, providing 125 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, 24.25-inch length, with injection-molded ABS end caps in a closed-bottom, open-top configuration seated on a Schedule-40 PVC core for axial rigidity at full operating pressure. Nominal filtration efficiency is 20 microns under standard test conditions. The element is rated for continuous service to 104°F and operating pressures up to 50 PSI, with UV-stabilized end cap adhesive formulated for chemical resistance under standard pool water chemistry. High-area construction enables extended service intervals between cleaning cycles and reduces ΔP rise rate under heavy bather load.

Service interval recommendation: residential installations — pressure-differential-based replacement triggered at ΔP ≥ 8–10 PSI above clean-filter operating baseline, or on an annual calendar cycle, whichever occurs first. Rinse the element every 4–6 weeks during the active season; perform a chemical soak (dilute TSP or commercial enzyme/degreasing cleaner) every 3–6 months to address oils and organic loading that resist water rinsing. For calcium scale accumulation, muriatic acid soak at 1:20 dilution is compatible with ABS end caps; limit exposure to 20 minutes and rinse thoroughly prior to reinstallation. Chlorine tolerance: continuous service at ≤ 10 ppm free available chlorine; enzyme cleaners compatible without restriction. Verify housing pressure post-installation against the clean-filter baseline and log for service records. Standard Unicel 90-day manufacturer's defect warranty applies through authorized distribution.
