Why Your Pool Deserves the Unicel C-9419
1. High-Capacity Filtration
The C-9419 boasts 200 sq. ft. of pleated Reemay® spunbond polyester, maximizing dirt-holding capacity. This means:
-
Fewer cleanings between cycles
-
Better capture of fine particles (down to 10–20 microns)
-
Consistent, powerful water flow through the filter system
2. Built to Withstand Pool Season After Season
This cartridge is designed for longevity under real-world pool conditions. The reinforced core resists collapse, even under high pump pressures. The molded end caps stand up to chlorine, algaecides, and other pool chemicals without cracking or weakening.
3. Direct OEM-Compatible Fit
Designed to match Pentair’s OEM dimensions, the C-9419 slides in effortlessly. No cutting, trimming, or adjusting — simply remove your old cartridge, insert the new Unicel, and you’re ready to enjoy cleaner water.

4. Lower Maintenance, Higher Efficiency
With its pleated design and open-core structure, the C-9419 ensures strong water flow and reduced pump strain. The result? Your system works more efficiently, potentially lowering your energy bills while keeping water circulation optimal.
The Science of Cleaner Water
The pleated polyester media increases surface area, allowing water to pass through while trapping debris on the surface and within the pleats. Unlike sand filters, which can allow smaller particles to pass through, or DE filters, which require messy powder handling, a cartridge filter like the Unicel C-9419 provides:
-
Ease of maintenance – No backwashing needed
-
Eco-friendliness – Conserves water by reducing waste discharge
-
Consistent performance – Maintains clarity without chemical overuse
Installation is Fast and Simple
-
Turn Off Your Pump: Always power down your filtration system before beginning.
-
Release Pressure: Open the air relief valve to prevent damage when opening the filter tank.
-
Remove Old Cartridge: Lift out the used filter, noting its positioning for correct replacement.
-
Insert the Unicel C-9419: Place the cartridge securely into the housing, ensuring a snug fit.
-
Reassemble and Test: Close the filter housing, restart your pump, and check for strong, steady water flow.
Pro Tips for Maximizing Cartridge Life
