Unicel C-7472 Cartridge Filter Set – 4-Pack Replacement
Premium Replacement Filter Set for Peak Pool Performance
Keeping your pool water pristine is about more than aesthetics—it’s about the health of your water and the longevity of your pool equipment. The Unicel C-7472 Cartridge Filter Set (4-Pack) delivers a complete system refresh for 320 sq. ft. Pentair® Clean & Clear® Plus, Predator®, and other compatible systems.
Made with 100% genuine Reemay® spunbond polyester filter media, precision-molded end caps, and a reinforced center core, these cartridges are built to outperform and outlast generic replacements. When used as a complete 4-cartridge replacement, they restore your filtration efficiency, reduce pump strain, and help maintain water clarity longer between cleanings.
Why Replace All Four Cartridges at Once?
Your pool’s cartridge filter system is designed for balanced filtration. Replacing just one or two cartridges at a time creates uneven flow, increases pressure on your pump, and shortens the lifespan of the remaining older filters.
By installing a full matching set of Unicel C-7472 cartridges, you:
-
Restore even water distribution
-
Maintain optimal flow rates
-
Reduce system pressure and pump workload
-
Extend the life of your pool equipment
This is the smart, preventative maintenance step that professional pool service companies recommend at least every 2–3 years—or sooner for high-use pools.
The Unicel C-7472 Advantage
1. Superior Filtration with Reemay® Media
Reemay® polyester is the gold standard for pool cartridge filters. Its dense, nonwoven fibers trap dirt, fine silt, oils, pollen, and algae spores down to 10–20 microns, all while allowing water to flow freely through the pleats.
2. OEM-Perfect Fit
With dimensions of 32.875" length x 7" diameter, each C-7472 cartridge fits exactly in place of Pentair’s original 80 sq. ft. cartridges. No trimming, forcing, or modification required.
3. Maximum Surface Area
The pleat count is engineered to maximize dirt-holding capacity while maintaining proper spacing for easy cleaning. This means longer intervals between cleanings and more time enjoying your pool instead of maintaining it.
4. Reinforced Structural Integrity
Unicel’s molded end caps and PVC center cores are chemical-resistant and strong enough to withstand repeated cleanings, high pump pressure, and temperature variations.
5. Built to Last Multiple Seasons
With proper maintenance, these cartridges can be cleaned and reused for several years, making them a cost-effective investment for pool owners.

Frequently Asked Questions (FAQ)
Q1: Can I replace just one cartridge instead of the full set?
You can, but it’s not recommended. A mismatched set causes uneven flow and reduced filtration efficiency.
Q2: How often should I replace my cartridges?
Typically every 2–3 years for residential pools, or annually for high-use or commercial pools.
Q3: Are these compatible with saltwater systems?
Yes—Unicel cartridges resist corrosion from both chlorine and saltwater pools.
Q4: What’s the micron rating?
These cartridges filter particles down to approximately 10–20 microns.
Q5: Can I use these in non-Pentair systems?
Yes—if the dimensions match your existing cartridges and your system requires 80 sq. ft. cartridges, these will fit.
Q6: How do I clean my cartridges?
Rinse with a garden hose regularly, and use a filter cleaner soak for deep cleaning at least once per season.
