Poolzilla PLF100A Replacement Pool Filter Cartridge for Pentair CC100 / Unicel C-9410 — Dirt‑Trap Pleated Media, 23.6" Length

Poolzilla PLF100A is a direct-fit replacement filter cartridge engineered to match Pentair Clean & Clear 100 and Unicel C-9410 dimensions while improving debris capture with its dirt-trap pleated fabric.

If your pool or spa uses a CC100-style cartridge, this Poolzilla replacement offers the same critical measurements—23 5/8" length, 10 1/16" outer diameter and 6" top and bottom openings—while using a pleated, dirt-trap media designed to catch more hair, sand and fine particles. It’s a compatible aftermarket part made to restore filtration performance without the OEM price tag, and it’s easy to clean and service during the season.

How does this cartridge fit my existing Pentair or Unicel system?

The PLF100A was manufactured to the common CC100/C-9410 footprint so it installs in the same filter housing and seals with the identical openings. You won’t need adapters when replacing a Pentair R173215 or Unicel C-9410 cartridge.

• Length: 23 5/8" (600 mm approx.)
• Outside diameter: 10 1/16"
• Top and bottom openings: 6" each
• Compatible references: Pentair R173215, Unicel C-9410, Filbur FC-0686

What makes Poolzilla’s "Dirt-Trap" fabric better than standard filter media?

Poolzilla uses a pleated media with a dirt-trap weave that increases surface area and retains finer particles compared with conventional round-fiber cartridges. The structure helps trap hair, silt, and small sediment while preserving flow rate even as debris collects.

• Enhanced pleating for larger effective filtration area
• Dirt-trap fabric captures fine contaminants and hair
• Designed to maintain flow rates under load
• Easier rinsing to remove trapped debris

How long will this replacement cartridge last and how do I maintain it?

With regular cleaning and normal pool conditions, expect a service life of roughly 1–2 years. Routine rinsing keeps the pleats clear; deep cleaning or a replacement schedule depends on bather load and the amount of debris in the water.

• Simple maintenance: remove and rinse with garden hose
• Deep clean periodically for heavily used pools or spas
• Typical lifespan: 1–2 years with proper care
• Replace sooner if pleats are torn or permanently stained

Will this cartridge improve water clarity and chemical performance?

By removing visible particles—sand, silt, rust and suspended solids—the cartridge helps produce clearer water and can reduce the workload on sanitizers. While it doesn’t change chemical formulations, cleaner water often means fewer odor and taste complaints related to particulate load.

• Removes sediment, rust particles and visible turbidity
• Reduces hair and large debris that accelerate equipment wear
• Frequent filtration helps maintain sanitary conditions when combined with proper chemistry

Who is this for? Poolzilla PLF100A is for pool and spa owners with CC100-style filter systems who want a cost-effective, high-performance aftermarket replacement. It’s ideal if you need a direct-fit cartridge with improved particle capture, easy rinse maintenance, and the exact dimensions required for Pentair Clean & Clear 100, Unicel C-9410, and equivalent models. If you prefer OEM compatibility without OEM pricing and want responsive customer support from a U.S.-based team, this cartridge is a practical choice.
