VEVOR Pool Filter Cartridge 4-Pack — 420 sq. ft. Pleated Spa/Hot Tub Replacement, 50‑Micron Trilobal Fiber

The VEVOR 420 sq. ft. pool filter cartridge 4-pack is a direct-fit replacement for Pentair CCP420-style systems, providing high-efficiency, NSF/EPA-certified filtration for pools and hot tubs.

These four VEVOR PCC105-PAK4 cartridges supply 420 total square feet of pleated filter media designed to trap fine debris while resisting pressure and wear. Built with trilobal fibers and a reinforced core, each cartridge mirrors the dimensions and fit of Pentair CCP420 and equivalent models (Unicel C-7471, Filbur FC-1977). The set is intended for owners who want a reliable, easy-to-rinse option for steady water clarity in residential pools and spas.

How do these cartridges improve water clarity?

The cartridges use tightly pleated trilobal fibers to increase surface area and capture particles down to approximately 50 microns. That combination boosts dirt-holding capacity so the filter traps more contaminants between cleanings, reducing cloudiness and extending run time.

• Trilobal pleated fiber for increased filtration area
• 50-micron rating to catch fine debris like dust and sand
• Four cartridges supply 420 sq. ft. total for larger filtration capacity

Will the VEVOR PCC105-PAK4 fit my Pentair CCP420 system?

Yes — these cartridges are made to match the size and connection style of Pentair CCP420 cartridges and common cross-reference numbers such as R173576. They fit systems that accept 26" length, 7" outer diameter, and 3" inner diameter cartridges without modification.

• Exact 26" length and 7" OD for direct compatibility
• 3" ID for proper seating on standard filter cores
• Cross-referenced with Pentair CCP420, Unicel C-7471, Filbur FC-1977

How durable and easy to maintain are these replacement filters?

The cartridges are built with a reinforced inner core and molded end caps to resist collapse and maintain shape under typical pool pressures. They’re engineered for repeated rinsing and routine maintenance, so you can extend service life through monthly cleanings while avoiding frequent replacements.

• Reinforced inner core for pressure resistance and longevity
• Molded end caps that seal and stabilize during operation
• Designed for repeat rinsing to reduce replacement frequency

What safety and performance standards do these filters meet?

Manufactured from materials certified to meet NSF/EPA guidelines, the cartridges are intended for pool and spa use and prioritize material safety as well as filtration performance. The certification supports use in residential water systems while meeting common regulatory expectations.

• NSF/EPA-certified materials for use in pools and hot tubs
• 50-micron filtration for effective debris capture
• Constructed to maintain performance under normal operating pressures

Who is this for: The VEVOR PCC105-PAK4 4-pack is aimed at homeowners, pool service professionals, and spa owners who need a direct-fit, high-capacity replacement for Pentair CCP420-style cartridges. It is a practical choice for those who value easy maintenance, certified materials, and a durable design that supports longer intervals between cleanings.
