Unicel CL340 C-7459-4 Filter Cartridge Set – 4-Pack
Premium 4-Cartridge Replacement Set for Jandy CL340 Pool Filters
Your pool’s filtration system is the heart of its cleanliness and clarity. If you own a Jandy CL340 cartridge filter system and your water has lost its sparkle, it might be time for a complete filter refresh. The Unicel Jandy Style CL340 C-7459-4 Replacement Filter Cartridge (4-Pack) delivers an OEM-quality fit with industry-leading filtration performance, ensuring your pool water stays clear, healthy, and inviting.
When all four cartridges are replaced together, you restore the full 340 sq. ft. of filtration area your CL340 system was designed to have. That means balanced water flow, lower pump strain, and fewer cleanings — saving you both time and money.
Why Choose the Unicel C-7459-4?
1. OEM-Quality Fit and Performance
The C-7459-4 cartridges are engineered to meet or exceed the specifications of original Jandy CL340 filters. The precision-molded end caps, reinforced cores, and exact dimensions ensure a drop-in fit without the need for adjustments or modifications.
2. Premium Filtration Media
Each cartridge features Reemay® spunbond polyester, a proven industry standard for pool filtration. The pleated fabric provides a high surface area for dirt capture while allowing water to flow freely, reducing strain on your pool pump and keeping your water consistently clear.

While you can replace cartridges individually, a full set replacement ensures:
-
Even water distribution across all four filters

Most pool owners replace their entire set every 12–24 months, depending on water conditions, cleaning habits, and usage.

While you can replace a single cartridge, replacing the full set restores original flow balance and filtration performance.
