HANXER Pool Filter Cartridge Replacement 105 sq.ft Pack of 4 — Trilobal Fabric & Reinforced End Caps

HANXER C-7471 is a 105 sq.ft. trilobal-fabric pool filter cartridge sold as a pack of four, designed to replace PCC105, Pentair CCP420, Filbur FC-1977 and similar models for efficient debris capture and long service life.

This four-pack of HANXER C-7471 replacement cartridges brings high-capacity trilobal filtration to above-ground and in-ground pool systems. Built with 105 square feet of filtration area per cartridge, reinforced center support and heavy-duty end caps, the design focuses on balancing flow with fine particle capture. The result is clearer water between cleanings and durable performance in common residential pool setups.

How does this cartridge compare to the original PCC105 or Filbur FC-1977 replacements?

The HANXER C-7471 matches the key dimensions and filtration area of the referenced models so it fits housings designed for PCC105 and FC-1977. Its trilobal fabric provides increased surface area and particle-trapping geometry without significantly raising pressure. Together with reinforced end caps and a sturdy center core, the cartridge aims to equal — or in many cases exceed — factory replacement longevity.

• Length: 26 1/16" and outside diameter: 7" for compatible fit.
• Filtration area: 105 sq.ft. to match original capacity.
• Reinforced center support and heavy-duty end caps for durability.

How does trilobal filtration fabric improve pool cleaning?

Trilobal fibers have a three-lobed shape that increases surface area and creates more nooks to trap fine particles compared with standard bonded fabrics. This geometry captures microscopic debris while maintaining steady water flow, limiting pressure spikes that force more frequent backwashing or rinsing. The design reduces cleaning frequency and helps keep filtration efficient longer between maintenance cycles.

• Higher particle-holding capacity than ordinary fabrics.
• Maintains flow rate to avoid unnecessary pressure rise.
• Reduces how often you need to rinse the cartridge.

What are the practical maintenance steps and lifespan expectations?

Rinse cartridges frequently with a garden hose to remove surface dirt and extend usable life; occasional deep-soak cleaning with a filter cleaner product can restore trapped oils and scale. How long each cartridge lasts depends on pool usage, water chemistry, and cleaning habits, but replacing cartridges on a regular schedule ensures the pump runs efficiently and water clarity remains consistent. Buying this four-pack lets you rotate replacements or keep spares on hand for seasonal swaps.

• Regularly rinse with clean water after heavy use or storms.
• Deep clean with a filter-specific solution when needed.
• Replace per manufacturer guidance or when flow and clarity decline.

Will these cartridges work in my existing filter housing?

The HANXER C-7471 is engineered to fit housings that accept PCC105, Pentair CCP420, PCC105-PAK4, and Filbur FC-1977 style cartridges. Verify your system accepts a 26 1/16" x 7" cartridge with 3" open top and bottom openings before purchase. If dimensions and inlet/outlet align, installation is straightforward: remove the old cartridge, check for debris in the housing, then seat the HANXER unit onto the center post and secure the lid.

• Check length and diameter against your existing cartridge.
• Confirm top/bottom opening size is 3" for proper fit.
• Simple swap: remove old unit, clean housing, install new cartridge.

Who is this for: Pool owners and maintenance professionals seeking an affordable, durable replacement cartridge that fits common PCC105/FC-1977 housings. The HANXER C-7471 pack of four is ideal for households that prefer having spares available, those who rotate filters seasonally, or service technicians stocking compatible, high-capacity cartridges to maintain steady filtration and reduce downtime.
