Overview

The Unicel C-4950 replacement cartridge is designed for pool and hot tub filtration, delivering a substantial filtration surface without taking up extra space.

How it helps your spa stay clean

The cartridge uses sharp, uniform pleats to promote consistent water flow and minimize pressure loss. By leveraging the full pleat surface, it can handle routine debris while still allowing for effective flow during standard filtration cycles. This balance can contribute to a smoother maintenance routine and reduced pump strain over time.
