AQUALTRA Pool Filter Cartridge 20 1/16" x 7" 4-Pack — 80 sq ft, washable polyester for CCP320/PCC80

AQUALTRA CCP320 replacement pool filter cartridges are washable, NSF-certified polyester cartridges designed to fit PCC80/CCP320-style systems and restore clean, clear spa and pool water.

These four replacement cartridges measure 20 1/16" long with a 7" outer diameter and a 3" top/bottom opening, providing about 80 sq. ft. of filtration area per cartridge. Constructed from BPA-free PET composite media with chlorine-resistant end caps and a polypropylene core, they’re engineered to trap common debris while withstanding regular exposure to sanitizers. The pack is compatible with a wide range of OEM numbers (PCC80, CCP320, Ultral-A5, C-7470, R173573, FC-1976, 178580, 817-0081), making it a practical swap-in for many hot tubs and small pools.

How does this filter improve water clarity?

These cartridges use layered polyester media and a “dirt-locking” fabric pattern to capture fine particles that ordinary filters miss. The structure increases surface area and helps hold trapped debris so it doesn’t wash back into your tub during normal flow.

• 80 sq. ft. filtration area per cartridge for greater particle capture
• Multi-layer polyester media traps hair, leaves, dust, and sand
• Dirt-locking fabric reduces re-suspension of trapped debris

Are these filters durable and easy to maintain?

AQUALTRA cartridges are built with NSF-certified materials and chlorine-resistant end caps for longer life in sanitized water. They’re washable and designed for repeated rinsing; cleaning every two weeks will help maintain flow rate and extend service life.

• BPA-free PET composite media resists breakdown from chlorine
• Removable rinsing keeps maintenance quick and inexpensive
• Polypropylene core and reinforced ends limit deformation under pressure

Will these cartridges fit my spa or pool system?

The pack’s external dimensions (20 1/16" length, 7" OD, 3" openings) match many PCC80/CCP320-style filters and several OEM part numbers. Always compare your existing cartridge measurements and connection style to confirm compatibility before buying.

• Compatible with PCC80, CCP320, Ultral-A5, C-7470 and other listed part numbers
• Standard 3" top/bottom openings for common housing alignments
• Sold as a 4-pack to replace multiple filters or keep spares on hand

How should I clean and care for these cartridges?

Rinse the cartridge with a garden hose and a gentle spray pattern to dislodge trapped debris; avoid using wire brushes or corrosive cleaners. Remove the filter from the housing before rinsing and allow to dry between deep cleans to prevent mildew.

• Rinse every two weeks under moderate water pressure
• Remove before any chemical soaking to protect end caps and core
• Store dry spares in a clean, ventilated area to prevent odor or contamination
