Benefits

The Unicel C-7471-4 4-Pack helps keep compatible Pentair Clean & Clear Plus 420 filters operating properly. Over time, filter cartridges can become clogged, frayed, collapsed, or chemically damaged, which may reduce water flow and make it harder to keep the pool clean.

Installing a complete new set of cartridges helps improve filtration balance inside the tank, reduce strain on the circulation system, and support clearer pool water. The pleated media design provides a large surface area for capturing debris while allowing proper water flow through the filter system.
