Swimara Hayward C150S Replacement Pool Filter Cartridge — 150 sq ft, 10‑Micron Trilobal

Swimara Pro Series 150 sq ft replacement cartridge for Hayward C150S delivers 10-micron filtration in a durable, easy-to-clean cartridge sized to fit your Hayward SwimClear C150S tank.

Replace worn or underperforming filters with a cartridge built to match the Hayward C150S footprint and flow characteristics. The Swimara Pro Series cartridge uses trilobal 10-micron media across 150 square feet of pleated surface for fine debris capture while preserving water flow. PU end caps, a reinforced polypropylene core, and pleat-retaining bands stabilize the pack for reliable seating and straightforward rinsing maintenance.

How does this cartridge improve water clarity without choking flow?

The cartridge balances fine-particle capture and open flow by using trilobal fibers that increase exposed surface area inside each pleat. That geometry traps particles down to about 10 microns while maintaining channels for water to move through the pleat pack, reducing rapid pressure spikes.

• 150 sq ft pleated area for greater dirt-holding capacity
• Trilobal 10-micron media captures fine debris while supporting steady flow
• Pleat bands maintain even spacing for open water passages

Will this cartridge physically fit my Hayward C150S filter housing?

Yes — the Swimara Pro Series is manufactured to the same dimensions as the Hayward SwimClear C150S replacement: approximately 10-1/8 inch outside diameter and 23-1/8 inch length with 4-inch open ends. Always verify your existing cartridge measurements before ordering to ensure a correct fit.

• Compatible with Hayward SwimClear C150S housing
• Replaces CX150XRE, CS150E, PA150S, C-9441, FC-1266 models
• Check OD, length, and open-end size before installation

How do I clean and maintain the Swimara Pro Series cartridge?

Routine maintenance is simple: depressurize the filter, remove the cartridge, and rinse with a garden hose following your system manual. The trilobal fiber shape and consistent pleat spacing encourage debris release so rinsing is more effective; clean the cartridge when filter pressure rises 7–10 psi above the clean starting pressure for best performance.

• Easier garden-hose rinsing thanks to fiber geometry and pleat bands
• Follow Hayward C150S or pump manual for depressurizing and reassembly
• Monitor pressure gauge; deep-soak or chemical cleaning for heavy build-up

What construction features make this cartridge durable?

The cartridge pairs molded polyurethane (PU) end caps with a reinforced polypropylene (PP) core to hold the pleat pack securely under typical pool operating conditions. Retaining bands around the pleat pack protect even spacing and help prevent early collapse or channeling, extending usable life while preserving performance.

• PU end caps support a secure, leak-free seating in the tank
• PP core resists collapse while supporting the pleat pack
• Pleat bands keep pleats uniform for consistent filtration

Who this is for: Pool owners and service technicians who need a high-surface-area, 10-micron replacement cartridge for Hayward SwimClear C150S systems. It suits installations that require reliable fine-particle capture without frequent flow loss, and for those who prefer a cartridge that rinses clean more easily during routine maintenance.
