POOLPURE PCC105-PAK4 Pool Filter Cartridge Replacement - 26in x 7in

In this review the POOLPURE PCC105-PAK4 replacement cartridge is evaluated for homeowners and pool operators seeking an affordable drop-in alternative to Pentair and similar branded cartridges. The bottom line: it delivers noticeably cleaner water and an easy, tool-free install while offering NSF/ANSI 50 certified materials safety. For anyone who needs a 26in by 7in cartridge with a 105 sq.ft. surface area and 50-micron fine filtration, this cartridge is worth consideration for routine maintenance and seasonal swaps.

Key Features

• Dimensions: The 26in length and 7in outside diameter provide a direct physical match for systems needing that size, making swapouts simple and dependable.
• Trilobal Filtration Fabric: The trilobal fiber structure offers greater adsorption surface area so the cartridge captures more debris and helps keep water clearer between cleanings.
• 50-Micron Fine Filtration: A high-efficiency 50-micron layer captures fine particles like dust, hair, and sand to improve clarity and reduce chemical workload.
• Dirt-Locking Technology: The patented dirt-locking structure traps waste securely yet releases it easily during rinsing, reducing cleaning time and effort.
• Durable Construction: Reinforced ABS end caps, a strengthened core, and thicker 4 oz. polyester fabric extend service life and reduce replacement frequency.
• NSF/ANSI 50 Certified Safety: Materials are tested for long-term water exposure to ensure no harmful substances are released into pool or spa systems.

Who It's For

This cartridge is best for residential pool owners and service technicians who run cartridge-style filters that accept a 26in x 7in unit and who want a cost-effective compatible replacement that mimics Pentair CCP420-style dimensions and performance. It suits seasonal maintenance, regular replacements, and people looking to lower ongoing filter costs while maintaining clear water.

Those who should look elsewhere include operators who require true OEM parts for warranty reasons or customers who need a cartridge designed for backwashing systems, since this unit is not designed to be backwashed and can be damaged if used that way.

Pros & Cons
