Poolzilla Pool Filter Cartridge Replacement for PA150S/C150S Systems — 150 sq.ft, 23-1/8 in length

Poolzilla’s 150 sq.ft replacement filter cartridge is a drop-in compatible spare for PA150S/C150S-style systems that restores clear, flowing pool water.

This replacement cartridge fits systems that accept 23 1/8" length cartridges with a 10 1/8" outside diameter and 4" top and bottom openings. It’s designed as a compatible aftermarket option for Hayward SwimClear C150S, CX150XRE, CS150E, Unicel C-9441, Spa-Daddy SD-01333 and other PA150S-style housings. Built from pleated filtration media with a focus on durability and dirt-holding capacity, the cartridge aims to balance long service life with easy maintenance.

How does this cartridge match my existing PA150S or C150S filter?

The cartridge uses the same overall dimensions and port sizes required by PA150S-style systems, so it installs like the original. Measure your current cartridge length and ports to confirm compatibility before ordering.

• Length: 23 1/8" — matches PA150S/C150S form factor
• Outside diameter: 10 1/8" for correct housing fit
• Top and bottom openings: 4" to align with your system plumbing

What performance can I expect from the Poolzilla cartridge?

This cartridge is constructed with pleated media engineered for high dirt-holding capacity and sustained water flow. It removes visible debris—leaves, hair, and sediment—while helping reduce cloudiness so pumps and chemical systems work more efficiently.

• 150 sq.ft rated surface area for extended filtration between cleanings
• Pleated fabric intended to retain sediment, rust and fine particles
• Designed to sustain flow rates even as debris builds up

How do I clean and maintain this filter to maximize longevity?

Regular rinsing with a hose is the simplest maintenance and will restore much of the cartridge’s performance. For deeper cleaning, soak in an appropriate filter cleaner following the cleaner’s instructions, then rinse thoroughly and let dry before reinstalling if recommended by the cleaner.

• Rinse with a garden hose after heavy use or visible clogging
• Use a filter cleaning solution periodically for stubborn oils or scale
• Typical service life: about 1–2 years, depending on pool conditions and maintenance

Will this aftermarket cartridge affect my pool chemistry or system warranty?

This Poolzilla cartridge is an independent-brand compatible replacement and not an OEM part; it should not change water chemistry but can improve clarity by removing particulates. Review your equipment warranty terms—some manufacturers limit coverage when non-OEM parts are used.

• Compatible performance, not an original manufacturer part
• Helps reduce turbidity and visible particles that challenge sanitizers
• Check your pump/filter warranty before installing aftermarket parts
