Full Product Description +
The Unicel C-7470-4 Filter Cartridges (4-Pack) is a complete replacement set designed to restore proper filtration performance in Pentair Clean & Clear Plus 320 and Waterway Crystal Water 325 pool filter systems. Each cartridge provides 80 square feet of filtration area, delivering a combined 320 sq. ft. total when installed as a full set.
Cartridge filters gradually become loaded with oils, fine debris, and contaminants that cannot be fully removed through cleaning alone. When cartridges are worn or “blinded,” water flow is restricted, system pressure increases, and filtration efficiency declines. Replacing all four cartridges at the same time restores balanced flow, proper pressure, and clear pool water.
Manufactured by Unicel, these cartridges are engineered to meet or exceed OEM performance standards for fit, durability, and filtration efficiency.
Why Replacing All Four Cartridges Matters
Multi-cartridge systems require uniform filtration.
Why this matters:
-
Restores proper water flow and system pressure
-
Prevents debris bypass inside the filter tank
-
Improves overall water clarity
-
Reduces strain on pumps and plumbing
-
Ensures even filtration across all elements
Replacing partial sets can lead to uneven flow and reduced performance—full replacement is recommended.
Designed for Clean & Clear Plus 320 / Crystal Water 325
The Unicel C-7470-4 cartridge set is designed specifically for:
-
Pentair Clean & Clear Plus 320
-
Waterway Crystal Water 325
Precise sizing, end-cap design, and internal support ensure a proper seal and reliable operation. Always confirm filter model compatibility before installation.
High-Quality Filtration Media & Construction
Each cartridge is constructed with durable pleated polyester filter media bonded to reinforced end caps for structural integrity. The pleated design maximizes surface area for efficient debris capture while maintaining consistent water flow.
Unicel cartridges are widely trusted by pool professionals for their long service life and dependable performance.
Installation & Service Notes
For best results:
-
Turn off the pool pump and relieve filter pressure
-
Open the filter tank and remove all four old cartridges
-
Inspect the tank interior and O-rings
-
Install all four new cartridges evenly
-
Reassemble the filter and restart the system
Cartridge replacement is typically recommended every 1–2 seasons, depending on pool usage and water conditions.
