POOLPURE PA150S Pool Filter Cartridge Replacement - 150 sq ft

In this review of the POOLPURE PA150S pool filter cartridge, the bottom line is simple: this compatible replacement is for pool owners who need a high-capacity, easy-to-service cartridge that restores clear water without replacing the full filter assembly. The reviewer found it a practical swap for Hayward C150S and CX150XRE style housings, offering 150 sq. ft of trilobal filtration fabric and a precise 50 micron rating, which together remove hair, leaves, sediment and fine particles while remaining straightforward to install and clean.

Key Features

• 150 sq. ft filtration area: Provides ample surface area to capture debris and lower the frequency of cartridge maintenance compared with smaller elements.
• Trilobal filtration fabric: The unique fabric increases effective surface area for improved particle capture and stable back pressure.
• NSF/ANSI 50 certified: Tested by IAPMO to ensure safe materials and consistent 50 micron performance for clearer pool water.
• Exact dimensions: At 23 1/8 in length and 10 1/8 in outer diameter, it fits compatible Hayward-style housings for a reliable replacement.
• Top and bottom 4 in openings: Standard openings make alignment and installation straightforward for most single-cartridge top-load systems.
• Easy maintenance: The fabric releases trapped stains and debris with monthly cleaning, simplifying upkeep.

Who It's For

This cartridge suits pool and spa owners running Hayward SwimClear C150S, CX150XRE, or PA150S style systems who want a cost-effective replacement cartridge with certified materials and good filtration capacity. It is especially useful for users who prefer replacing cartridges rather than retrofitting new filter tanks.

Those who should look elsewhere include owners needing a backwash-capable element or people who require a cartridge with a different micron rating; this product is not designed for backwashing and using it that way can cause damage.
