Swimara Pool Filter Cartridge for Hayward C1750 — 175 sq ft, 10‑Micron Trilobal Media

The Swimara Pro Series cartridge is a direct-fit 175 sq ft replacement filter for Hayward C1750 systems that captures fine debris down to 10 microns while preserving steady water flow.

Engineered as a high-performance alternative for Hayward C1750 and compatible models, this Swimara Pro Series cartridge balances fine filtration with easy maintenance. Its 3 oz/sq yd trilobal media and reinforced construction deliver consistent particle capture, and the molded end caps and pleat bands help the cartridge sit securely and rinse clean. Certified to NSF/ANSI 50, it matches common cross references and fits the physical dimensions of many commercial-style pool filters.

Will this cartridge fit my Hayward C1750 or similar filter?

Yes — the Swimara Pro Series is dimensioned to replace Hayward C1750 units and many equivalent models. Confirm compatibility by checking overall area and dimensions against your current cartridge before ordering.

• Fits Hayward C1750 and same-size C1900 models
• Cross references include CX1750RE, PA175, C-8417 and FC-1294
• Dimensions: 175 sq ft; 8-15/16 in. outer diameter; 28-3/16 in. length; 4 in. open ends
• Also compatible with Waterway ProClean 175/200 when dimensions match

How fine is the filtration and what technology does it use?

The cartridge uses trilobal synthetic fibers with a 10-micron nominal rating to trap small particles while maintaining flow. The three-lobed fiber shape increases effective surface area and helps debris lodge in the media instead of clogging surface pleats immediately.

• Media weight: 3 oz/sq yd trilobal 10-micron synthetic media
• Improved surface exposure captures finer particulates compared with flat fibers
• Designed to maintain steady flow even as it loads with debris

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

Routine maintenance is straightforward: depressurize the filter, remove the cartridge and rinse with a garden hose to remove trapped debris. The trilobal media and evenly spaced pleats are designed to release material more readily during rinsing, which shortens cleaning time between deep cleans.

• Rinse with a garden hose after depressurizing the system
• For Hayward C1750/C1900, clean when pressure rises 7–10 PSI above clean starting pressure
• Occasional chemical cleaning may be needed for oils or mineral buildup per manufacturer guidelines

What construction features affect durability and fit?

Swimara built this cartridge with molded PU end caps, a reinforced polypropylene core and pleat-retaining bands to improve seating, structural support and even pleat spacing. Those elements reduce distortion under pressure and help the cartridge keep consistent flow characteristics throughout its service life.

• Molded PU end caps for secure seating and leak resistance
• Reinforced PP core supports the pleat pack under load
• Pleat bands preserve even spacing for open flow paths and easier rinsing
• Manufactured to meet NSF/ANSI 50 performance expectations

Who is this for: Pool owners, service technicians and facility managers who need a reliable, direct-fit replacement for Hayward C1750/C1900-style cartridges and want finer debris capture without sacrificing flow. If you require a 175 sq ft cartridge with robust construction, easy garden-hose cleaning and recognized certification, the Swimara Pro Series is designed to meet those needs. Always verify your filter’s model and cartridge dimensions before purchasing to ensure compatibility.
