AQUALTRA Pool & Spa Replacement Filter Cartridge 100 sq ft — 23 5/8" x 10 1/16" 2-Pack, Pleated PET Durable Washable

AQUALTRA’s 100 sq. ft. replacement pool and spa filter cartridge fits CC100/C-9410/PAP100 style housings to trap hair, leaves, sand and fine sediment for clearer water.

This two-pack of AQUALTRA filter cartridges is sized to match popular CC100/C-9410/PAP100 models and offers a high-filtration surface area in a durable, washable PET composite construction. Made from NSF/ANSI-certified materials with chlorine-resistant end caps, these cartridges are intended to be an affordable, reusable replacement for aging or clogged originals so your hot tub, spa or pool pump works more efficiently and your water stays cleaner between maintenance cycles.

How does this filter improve water clarity quickly?

The AQUALTRA cartridge uses a high-area pleated fabric and a "dirt-locking" design that captures both visible debris and finer particles that ordinary filters miss. As water moves through the pleats, contaminants cling to the media instead of being pushed through the element, producing noticeably clearer water after a single circulation cycle.

• 100 sq. ft. filtration area captures more debris per cycle
• Fine pleated PET composite traps sand, dust, hair and pollen
• Dirt-locking weave reduces re-entrainment of particles
• Chlorine-resistant end caps maintain seal integrity longer

Will this fit my CC100, PAP100 or C-9410 housing?

Measure your existing cartridge to confirm compatibility: outer diameter 10 1/16" and length 23 5/8" with a 6" top and bottom opening are the critical dimensions. AQUALTRA lists this cartridge as compatible with many OEM numbers including CC100, PAP100, C-9410 and their equivalents, but you should always double-check your model before ordering.

• Outer diameter: 10 1/16"; length: 23 5/8"
• Top & bottom opening: 6"; filtration area: 100 sq. ft.
• Cross-references: CC100, PAP100, C-9410, Ultral-C3, R173215, FC-0686
• AQUALTRA is an independent brand; OEM names shown for compatibility only

How do I clean and maintain these reusable cartridges?

These filters are designed to be rinsed and reused to extend service life and reduce waste. For routine care, remove the cartridge and rinse with a hose every two weeks; a deeper soak with a filter-cleaning solution periodically will remove oils and finer grime.

• Rinse with a garden hose to remove loose debris
• Soak in a filter cleaner for stubborn oils or scale build-up
• Allow to dry fully before reinstalling for best performance
• Remove filter from housing before cleaning to avoid corrosion

What durability and safety features are included?

AQUALTRA cartridges are assembled using BPA-free PET composite media and chlorine-resistant end caps tested to NSF/ANSI standards. Those materials resist breakdown from routine sanitizers and extend the life of the filter compared with lower-grade replacements.

• NSF/ANSI-certified PET composite filter media
• High chlorine resistant end caps for longer seal life
• BPA-free components for safer spa and pool use
• Washable fabric construction supports multiple reuse cycles

Who is this for: Owners of spas, hot tubs and above- or in-ground pools that accept CC100/C-9410/PAP100-style cartridges who want a reliable, reusable two-pack replacement with wide cross-reference compatibility. This product suits budget-conscious buyers who prefer washable filters, maintenance-minded users who clean cartridges regularly, and anyone replacing old or damaged elements to restore pump efficiency.
