Unicel C-3310AM Replacement Filter for Master Spas ELE-10AM | 8 Sq. Ft.

Overview

The Unicel C-3310AM is a pleated polyester antimicrobial spa cartridge filter element engineered for Master Spas circulation systems, delivering 8.0 sq ft of filtration area through a low-profile, single-element form factor. Media construction utilizes Reemay-grade nonwoven polyester treated with an integrated antimicrobial agent that inhibits bacterial and fungal colonization on the fabric surface between service intervals — a critical specification for the elevated-temperature, high-bather-load environment of dedicated spa applications. End cap configuration features ABS injection-molded top and bottom caps with the standard Master Spas threaded-base interface for direct manifold seating. Nominal filtration efficiency is 20 microns. Maximum rated continuous service temperature is 115°F with intermittent excursions to 120°F acceptable; operating pressure range conforms to the 5–15 PSI envelope typical of spa circulation pumps. The antimicrobial fabric treatment extends usable service life under continuous-duty residential spa operation relative to untreated polyester equivalents.

Service interval recommendation: rinse with fresh water every 2–4 weeks; chemical soak in dilute TSP or dedicated cartridge cleaner every 4–6 weeks to remove body oils, lotions, and surfactant residue that standard rinsing cannot extract. Element replacement is recommended at 12-month intervals for typical residential spa use, or at ΔP ≥ 5 PSI above clean operating baseline, whichever occurs first. The antimicrobial treatment supplements but does not replace standard sanitizer maintenance; maintain free chlorine at ≤ 10 ppm or total bromine at ≤ 30 ppm for fabric compatibility. Muriatic acid soak at 1:20 dilution is compatible for calcium scale removal (20-minute maximum exposure, thorough rinse required); enzyme cleaners compatible without restriction. Verify ozone compatibility with sanitization system specification before deployment in ozone-primary installations. Standard Unicel 90-day manufacturing defect warranty applies through authorized distribution.
