Consistent filtration performance is essential for maintaining clear, healthy pool water—especially in large cartridge filter systems. The Unicel C-7488 Replacement Filter Cartridge Set is a premium OEM-equivalent solution designed specifically for Hayward C4025 and C4030 cartridge pool filters. This complete 4-cartridge set restores full filtration capacity, ensuring balanced flow, efficient debris removal, and reduced system strain.

Over time, cartridge filters accumulate oils, debris, and fine particles that restrict water flow and reduce filtration efficiency. Replacing all cartridges as a matched set helps maintain even pressure across the filter tank and prevents premature wear on pumps and internal components.

Unicel is widely trusted by pool professionals for consistent pleat quality, strong core construction, and reliable micron-level filtration.

Restores Full Filtration Capacity and Water Clarity

A full cartridge set replacement is critical for large-format filters like the Hayward C4025 and C4030. Uneven or partially replaced cartridges can cause flow imbalance and reduced efficiency.

The Unicel C-7488 cartridges restore proper water flow and filtration surface area, helping capture fine debris and maintain crystal-clear pool water.

Designed Specifically for Hayward C4025 & C4030 Filters

These cartridges are manufactured to precise dimensions and specifications required for Hayward’s large cartridge filter systems. Proper fit ensures a tight seal, prevents bypass, and maintains correct internal pressure.

Using the correct cartridge set protects filter internals and supports long-term system reliability.

Heavy-Duty Pleated Media with Reinforced Core

Unicel cartridges are constructed with high-quality pleated filtration media bonded to a reinforced core. This design resists collapse, tearing, and deformation—even under high flow conditions.

The durable construction supports repeated cleanings and extended service life when properly maintained.

Why Replacing All Cartridges as a Set Matters

Large cartridge filters rely on balanced flow across all elements.

Replacing the full set helps:

• Restore proper filtration efficiency

• Maintain balanced internal pressure

• Improve water clarity

• Reduce pump and filter strain

Partial replacement can lead to uneven wear and reduced performance.
