Poolzilla Pool Filter Cartridge PLF90A Replacement — 17 3/8" x 8 15/16" Pleated Dirt‑Trap, 1‑Pack

Poolzilla PLF90A replacement cartridge is a direct-fit pleated pool filter designed to restore clear water for systems that use Pleatco PA90, Hayward Star Clear Plus C900 / CX900-RE, Unicel C-8409 and similar models.

When your pool filter is clogged or no longer captures fine debris, swapping in a high-quality replacement cartridge quickly improves circulation and clarity. This Poolzilla cartridge measures 17 3/8" long with an 8 15/16" outside diameter and 4" top and bottom openings, making it compatible with a wide range of popular residential and commercial filter housings. It’s engineered to trap common contaminants while keeping flow rates steady through the swimming season.

How does this cartridge match my existing filter model?

The Poolzilla PLF90A is built to the same external dimensions and port sizes as Pleatco PA90 and other referenced part numbers, allowing a straightforward swap without modifying the housing. You can compare the length, outside diameter, and opening sizes to confirm fit before purchase.

What filtration performance can I expect during the season?

This cartridge uses a pleated media and Poolzilla’s Dirt‑Trap design to collect more particulates than a simple round fabric. That raises clarity and reduces visible sediment, leaves, and bug debris while maintaining useful flow through the pump.

• Pleated fabric increases surface area for better contaminant capture.
• Traps sediment, sand, silt, leaves, and small organic debris effectively.
• Maintains higher flow rates even with moderate buildup.

How do I clean and prolong the life of the filter cartridge?

Routine rinsing keeps the pleated media performing well: remove the cartridge, spray with a garden hose, and repeat as needed. For heavier deposits, a soak in a cartridge cleaner will restore performance. With regular maintenance, the typical service life ranges from one to two seasons depending on pool use and water conditions.

• Rinse with a hose after every few weeks of use or when pressure rises.
• Use a filtered‑cartridge cleaning solution for deep dirt, oils, or algae.
• Inspect pleats for tears and replace when fabric integrity declines.

Will this replacement reduce chlorine taste or improve water clarity?

The cartridge removes physical contaminants that cause cloudiness and some causes of off‑tastes and odors. While it does not change chemical sanitizer levels, removing particulate load helps sanitizers work more effectively and often reduces visible turbidity and minor odor sources.

• Removes suspended particles that scatter light and cause cloudiness.
• Reduces organic debris that can contribute to odors and chlorine demand.
• Supports better sanitizer efficiency by lowering contaminant load.

Who is this for: Pool owners, maintenance professionals, and commercial facility managers who need a reliable, direct‑fit replacement cartridge for common filter housings. If your system uses Pleatco PA90, Hayward C900/CX900‑RE, Unicel C‑8409 or the listed equivalents and you want an affordable, durable option to restore filtration performance, the Poolzilla PLF90A is engineered for straightforward installation and dependable seasonal service.
