How does this cartridge fit my existing Pentair Clean & Clear 520 system?

The Tier1 cartridge is manufactured to the same external dimensions as the Pentair CCP520 and other cross-reference part numbers, ensuring a reliable, leak-free fit in compatible housings. It uses standard end caps and a central core designed to seat securely for everyday filtration.

• Exact dimensions: 32-1/16" height x 7" diameter for correct sealing
• Compatible with many cross-references: Pleatco PCC130, Filbur FC-1978, Unicel C-7472, and more
• Engineered end caps and core for a snug installation

What makes trilobal dirt-lock media better than standard fibers?

Trilobal fibers have a three-lobed cross-section that increases surface area and mechanical entrapment, catching more fine particles without clogging as quickly as some round-fiber cartridges. The design improves dirt-holding capacity while maintaining water throughput.

• Captures up to 40% more debris versus standard round fibers
• Traps hair, leaves, sand, and fine particulates effectively
• Helps preserve flow so pumps operate efficiently

Will this cartridge affect pump performance or heater function?

No — the Tier1 replacement includes an internal high-flow core that encourages steady circulation and avoids large pressure increases that can stress pumps or limit heater effectiveness. It’s built to balance filtration efficiency and hydraulic performance.

• High-flow core supports consistent water circulation
• Reduces likelihood of pressure spikes that can trigger maintenance
• Compatible with standard pool plumbing and pump setups

Is the cartridge tested for reliability and safety?

This cartridge has been tested to NSF 50 standards for pool and spa equipment, indicating it meets independent performance and durability benchmarks. Regular inspection and cleaning help maintain those results season after season.

• Independently tested to NSF 50 protocols
• Durable construction for repeated cleanings and reuses
• Designed for consistent water clarity when used properly
