Puri Tech PA175 Pool Filter Cartridge 175 sq ft Replacement for Hayward/Sta‑Rite — Trilobal Media, Reinforced End Caps

The Puri Tech PA175 is a 175 sq ft replacement pool and spa filter cartridge engineered to restore high‑flow, deep‑capture filtration for Hayward CX1750RE Star Clear Plus C1750, Sta‑Rite PXC‑175 and equivalent models.

When your pool filter performance falls off, swapping in a high‑capacity cartridge is the fastest way to regain clear water and normal system pressure. The PA175 uses trilobal synthetic media and reinforced end caps to hold pleat shape, increase debris capacity, and resist deformation during regular backwashing or rinsing. It's sized to match common OEM part numbers (PA175, C‑8417, FC‑1294, 46193/303743, 223343) and measures approximately 8 15/16" x 4" x 28 3/16" for a direct fit in compatible housings.

How does the PA175 improve filtration compared with a worn cartridge?

Fresh trilobal media exposes more surface area to the flow, so water sees more fabric before passing through, which captures finer particulates and bulk debris alike. The pleat geometry and stable end caps preserve consistent flow patterns and prevent collapse under normal pump pressure.

• 175 square feet of trilobal filtration fabric for increased capture area
• Pleat spacing engineered to hold more debris between cleanings
• Reinforced end caps reduce distortion and maintain consistent pressure

Is this cartridge compatible with my Hayward or Sta‑Rite filter?

The Puri Tech PA175 is designed as a direct replacement for Hayward CX1750RE Star Clear Plus C1750, Sta‑Rite PXC‑175 and other like models using the PA175/C‑8417/FC‑1294 family. Check overall length and diameter against your existing cartridge to confirm fit before purchase.

• Fits models listed: Hayward CX1750RE Star Clear Plus C1750, Sta‑Rite PXC‑175
• Also cross‑references PA175, C‑8417, FC‑1294, 46193/303743, 223343
• Nominal size: 8 15/16" x 4" x 28 3/16" — verify with your unit

How do I clean and maintain the cartridge for long life?

The trilobal fibers trap debris deep in the pleats but release it efficiently with a steady rinse, restoring much of the original performance without aggressive chemical treatments. Regular monthly rinsing and occasional soak with an approved cartridge cleaner will extend service life and help maintain peak flow.

• Rinse with a steady garden hose spray between pleats after removal
• Soak periodically in a manufacturer‑recommended cartridge cleaner for deep oil or mineral removal
• Inspect end caps and pleats for damage; replace if torn or permanently deformed

What construction features affect durability and performance?

The PA175 combines a high‑capacity, trilobal polypropylene media with sturdy molded end caps to resist cyclical pressure and handling. That combination preserves pleat geometry for reliable filtration efficiency and helps the cartridge tolerate routine cleaning cycles.

• Trilobal fiber increases effective surface area versus point‑bond fabrics
• Durable molded end caps maintain seal and alignment in the filter housing
• Uniform pleat spacing promotes balanced back pressure and consistent flow

Who is this for: Pool and spa owners, service technicians, and maintenance pros who need a cost‑effective OEM‑compatible replacement cartridge that restores flow and filtration capacity. If your filter shows elevated pressure, cloudy water, or frequent run times, the Puri Tech PA175 offers a high‑surface‑area, durable option sized for common Hayward and Sta‑Rite systems.

• Features: Advanced trilobal fabric, high debris capacity, easy clean recovery, reinforced pleats and end caps, made in USA.
• Uses: Monthly maintenance, pressure‑based cleaning cycles, and routine seasonal cartridge replacement.
