Grefilt Pool Filter Cartridges 4-Pack CCP320 320 sq.ft — 30-Micron Trilobal Fabric, ABS End Caps

Grefilt's 4-pack CCP320 cartridges are direct-fit 320 sq.ft. replacement pool filters engineered for 30-micron performance, longer service life, and reliable compatibility with Pentair Clean & Clear Plus 320-style systems.

These cartridges offer a high-filtration alternative when you need to refresh your pool's circulation system. Built from 5 oz heavy-duty trilobal fabric and reinforced with a sturdy core and ABS end caps, the Grefilt CCP320 set balances efficient particle capture with stable flow. NSF/ANSI 50 testing confirms material safety for pool and spa use, while design upgrades reduce clogging and extend time between cleanings.

How do these cartridges improve water clarity without choking your pump?

The Grefilt CCP320 uses a trilobal fiber weave and 30-micron nominal filtration to trap fine debris while maintaining steady circulation. Its uniform fiber distribution reduces localized clogging and pressure spikes so the pump doesn't have to work harder to push water through the media.

• 30-micron precision filtration captures fine particles for clearer water
• Trilobal fibers increase surface branches for better particle capture
• Uniform fabric layout preserves flow, minimizing pressure rise

Will these cartridges fit my Pentair Clean & Clear Plus 320 or similar system?

Grefilt CCP320 cartridges are made to match the common dimensions of 320 sq.ft. replacement cartridges used in many models labeled Clean & Clear Plus 320. They are a compatible replacement, not an OEM part, so you should verify your current filter measurements before ordering.

• Length: 20 1/6" and outside diameter: 7"
• Top & bottom opening: 3" to match standard cores
• Replaces Pentair R173573 and Pleatco PCC80-PAK4 style cartridges

How durable are these cartridges and what extends their lifespan?

Durability is increased through a combination of thicker 5 oz fabric, reinforced ABS end caps, and an integrated support core. This structural strength helps the cartridge resist deformation and maintain filtering efficiency under normal pool pressures.

• Thickened 5 oz trilobal filtration fabric for wear resistance
• High-strength ABS end caps for secure sealing and longevity
• Support core prevents collapse and extends usable life up to ~30%

Is this product safe for family pools and spas?

Yes—materials used in these cartridges have been tested to NSF/ANSI 50 standards, which evaluate safety for pool and spa components. That certification indicates the filter media and construction meet recognized criteria for materials coming into contact with recreational water.

• NSF/ANSI 50 certified materials for peace of mind
• Compatible with typical residential pool chemical routines
• Designed to trap contaminants without releasing harmful substances

Who is this for: The Grefilt 4-Pack CCP320 is aimed at pool owners and service professionals who need a dependable, cost-effective replacement set for 320 sq.ft. cartridge filters—especially those using Pentair-style Clean & Clear Plus systems or equivalent models. If you want better particle capture, longer intervals between cleanings, and NSF-tested materials, this 4-pack is built to meet seasonal pool maintenance demands.
