AQUALTRA Pool Filter Cartridge 26" x 7" (4-Pack) — 105 sq. ft. Pleated PET, Chlorine-Resistant End Caps

AQUALTRA's CCP420-compatible pool filter cartridge is a 26" x 7" pleated replacement designed to trap hair, leaves, sand and fine sediment while restoring flow for home pools, spas and hot tubs.

This four-pack of replacement cartridges fits a wide range of filter housings that use 26-inch by 7-inch elements with 3-inch top and bottom openings. Built from NSF-certified PET composite media with a polypropylene core and chlorine-resistant end caps, these cartridges are washable and reusable to cut maintenance costs and keep water clearer between deep cleans. Compatibility references include Pentair part numbers and other commonly used model IDs so you can confirm fit before purchase.

How does this cartridge improve my pool or spa water clarity?

The pleated fabric and "dirt-locking" weave capture both coarse debris and finer particulates, reducing cloudy water and visible contaminants. Restored flow from a clean cartridge helps filtration systems run more efficiently, improving turnover and circulation.

• 105 sq. ft. filtration area to catch more particles per cartridge
• Pleated PET composite media for improved dirt-holding capacity
• Chlorine-resistant end caps to preserve seal integrity
• Compatible with common Pentair and aftermarket housings for quick replacement

Will this fit my existing filter housing and how do I confirm compatibility?

Measure your old cartridge: the AQUALTRA replacement is 26" long, 7" outer diameter, with 3" openings at each end. The product lists compatible model numbers for cross-reference, but always compare physical dimensions and top/bottom opening sizes before ordering.

• Length: 26 inches; outer diameter: 7 inches
• Top and bottom opening diameter: 3 inches
• Common cross-reference: Pentair 178584, CCP420, C-7471, FC-1977
• Check your housing part number or remove old cartridge to verify fit

How do I clean and maintain these washable cartridges?

Rinse cartridges every two weeks under low-pressure water to remove trapped debris; deep-cleaning can be done with a filter-cleaning solution as needed. Always remove the cartridge from the housing before rinsing and allow it to fully dry if using chemical cleaners.

• Recommended light cleaning interval: every 2 weeks for regular use
• Use garden hose rinse for routine cleaning; filter cleaner for heavy buildup
• Remove cartridges from housing before cleaning to avoid corrosion
• Reinstall only when fully seated and dry if chemical cleaners are used

What materials are used and are they durable in chlorinated water?

The cartridge uses PET composite filter media, a polypropylene core and chlorine-resistant end caps, all free of BPA and certified to NSF/ANSI standards for material safety. These components are selected to resist degradation from typical pool and spa chemicals, extending usable life when maintained properly.

• PET composite media resists tearing and holds fine particulates
• Polypropylene core maintains structural support under flow
• Chlorine-resistant end caps protect seal surfaces from chemical wear
• NSF/ANSI-related material certification for safer leisure use

Who this is for: AQUALTRA's 26" x 7" CCP420-compatible 4-pack suits homeowners and pool service techs who need a cost-effective, reusable replacement for common cartridge housings. If you operate a residential pool, spa or hot tub that uses the listed dimensions or cross-reference part numbers, this pack reduces downtime, replenishes filtration performance and lowers long-term filter expenses. Always confirm dimensions and model compatibility before buying.
