POOLPURE PXST175 Pool Filter Cartridge 1-Pack — 50‑Micron, 175 sq ft High-Capacity Direct-Fit Replacement

The POOLPURE PXST175 is a direct-fit replacement pool filter cartridge engineered to match Hayward X-Stream CCX1750-RE performance, delivering high-efficiency 50-micron filtration and extended service life.

If your pool uses a Hayward X-Stream-style cartridge and you need a reliable, high-capacity replacement, the POOLPURE PXST175 is built to slot in and restore clear, low-maintenance filtration. This replacement cartridge is constructed from trilobal polyester fabric with a dirt-locking structure, reinforced end caps, and a strengthened core. It provides 175 square feet of filtration area and is sized to the same dimensions as the OEM-style CCX1750 family so installation is straightforward.

How well does this cartridge remove fine particles?

The PXST175 uses a 50-micron filtration layer combined with a trilobal fiber design that increases adsorption surface area, improving capture of fine debris. That results in clearer water and less frequent deep cleaning compared with coarse cartridges.

• 50-micron fine filtration captures hair, dust, sand, and pollen.
• Trilobal fabric offers roughly three times the surface adsorption versus conventional fibers.
• 175 sq. ft. filtration area provides higher dirt-holding capacity for longer run times.

Will this cartridge fit my existing Hayward X-Stream or Unicel system?

Yes — the POOLPURE PXST175 is dimensioned to be compatible with Hayward XStream CC1750, CCX1750RE, PXST175, PXST175-M and common equivalents like Unicel C-8317 and FC-1301. The top and bottom openings, outer diameter, and length match OEM-style cartridges for simple replacement.

• Length: 23 5/16"; Outer diameter: 8 15/16"; Top/Bottom openings: 4".
• Direct-fit design for CCX1750 family and Unicel equivalents.
• No special tools required — remove old cartridge, insert new, reseal housing.

How durable and low-maintenance is this replacement cartridge?

The PXST175 is built with heavier polyester fabric and reinforced ABS end caps, plus an integrated strengthened core to resist collapse and wear. Its patented dirt-locking technology releases trapped debris more easily during rinsing, lowering maintenance time and extending usable life.

• 4 oz. thickened polyester fabric for longer lifespan than standard cartridges.
• Reinforced end caps and core reduce collapse risk and replacements.
• Easy rinse-and-reuse design minimizes chemical and cleaning frequency.
