Unicel C-5315 Replacement Filter for Intex 59905 | 15 Sq. Ft.

Overview

The Unicel C-5315 is a pleated polyester cartridge filter element engineered for above-ground pool applications, providing 15.0 sq ft of filtration area in a compact disposable-style form factor. Media construction is Reemay nonwoven polyester with nominal 20-micron filtration efficiency, configured in a high-pleat-count geometry to maximize surface area within the constrained envelope of above-ground filter housings. The element utilizes a coreless construction with molded ABS end caps featuring matching open-bore geometry on both ends, conforming to the Intex "Type B" interface standard. Rated for continuous service to 104°F at operating pressures consistent with above-ground cartridge pump systems (typical 5–15 PSI range). Pleat-pack rigidity is maintained through media stiffness alone, appropriate for the low-flow, low-differential service conditions of this product class.

Service interval recommendation: above-ground and seasonal pool installations — rinse with fresh water every 1–2 weeks during active season; replace at ΔP ≥ 5 PSI above clean-filter operating baseline, or every 2 weeks under heavy bather load, whichever occurs first. End-of-season replacement is standard practice; storage of used cartridges is not recommended due to biofilm establishment risk. Chemical compatibility: polyester media tolerates continuous service at ≤ 10 ppm free available chlorine and is compatible with bromine sanitization. Enzyme cleaner compatible without restriction; muriatic acid soak at 1:20 dilution acceptable for calcium scale, though typically not required given the disposable service profile of this product class. Standard Unicel 90-day manufacturing defect warranty applies through authorized distribution.
