POOLPURE PLF90A Pool Filter Cartridge 90 sq.ft - Reliable Replacement

In this review the POOLPURE PLF90A is presented as a practical replacement cartridge for owners of compatible filter housings who want strong filtration at a lower cost. The bottom line: this two-pack offers 90 sq.ft of trilobal filtration fabric per cartridge and certified material safety, making it a sensible choice for pool and spa users prioritizing particle removal and easy maintenance. It is aimed at people who need a like-for-like replacement for common Hayward, Pleatco, Unicel and Sta-Rite models without paying a premium for brand-name parts.

Key Features

• Precision Filtration: Certified to NSF/ANSI 50 and rated at about 50 microns, the cartridge effectively captures hair, leaves, dust and fine sediment for clearer water.
• Generous Surface Area: The 90 sq.ft of trilobal filtration fabric increases the effective filtering area, improving dirt-holding capacity and maintaining consistent flow.
• Standard Size Fit: With a length of 17 3/8 in and an outside diameter of 8 15/16 in and 4 in top and bottom openings, it fits housings designed for Hayward C900/CX900RE and similar models.
• Easy Cleaning: The uniform trilobal fabric releases trapped debris easily during rinsing, simplifying monthly maintenance and reducing downtime.
• Two-Pack Value: Sold as a pair, the set delivers immediate backup spares so users can swap and clean without interrupting filtration.

Who It's For

The POOLPURE PLF90A is best for pool and spa owners running filter systems compatible with Hayward CX900RE/C900 series, Pleatco PA90, Unicel C-8409, Sta-Rite PXC-95 and similar cartridges who want a lower-cost replacement that still meets safety standards. It suits DIY maintainers who clean cartridges regularly and need a two-pack to keep one in use while the other is rinsed.

It may be less suitable for buyers who insist on OEM-branded parts for warranty reasons or for those who require specialized materials beyond the trilobal filtration fabric; some customers report mixed long-term durability, so users seeking the absolute longest-lived OEM cartridge might look elsewhere.
