Unicel C-9450AM Replacement Filter for Waterway 500-0168AM | 150 Sq. Ft.

Overview

The Unicel C-9450AM is a pleated polyester cartridge filter element configured for large-capacity residential and light commercial pool filtration applications, delivering 150 sq ft of effective filtration area through a high-pleat-count nonwoven polyester media pack with antimicrobial treatment (denoted by the "AM" suffix in the Unicel part number nomenclature). The element is constructed on a structural PVC core with molded ABS end caps — closed-bottom, open-top configuration — providing axial rigidity under sustained operating pressure. Antimicrobial-impregnated media inhibits bacterial and fungal colonization within the pleat substrate, extending serviceable life between chemical cleanings and reducing biofilm-related ΔP drift in moderate-bather-load installations. Standard operating temperature ceiling is 104°F continuous; pressure rating supports residential and light commercial pump head curves within standard 8–25 PSI operating windows.

Service interval recommendation: pressure-differential-based replacement triggered at ΔP ≥ 8–10 PSI above clean-filter operating baseline, with annual calendar replacement as the outside limit under typical residential bather loads. Rinse with fresh water every 4–6 weeks during operating season; chemical soak (dilute TSP or commercial enzyme cleaner) every 3–6 months to remove oils, surfactants, and organic loading that resist mechanical rinsing. For calcium scale accumulation, the element is compatible with muriatic acid soak at 1:20 dilution, 20-minute maximum exposure; rinse thoroughly before reinstallation. Chlorine tolerance: continuous service at ≤ 10 ppm free available chlorine; bromine compatible. Antimicrobial media treatment supplements but does not replace standard sanitizer maintenance — verify free chlorine residual independently. Standard Unicel 90-day manufacturing defect warranty applies through authorized distribution.
