Hayward replacement cartridge for StarClear Plus C1200 — CX1200RE 100 sq ft reinforced polyester, extruded core

If your pool's StarClear Plus C1200 filter is showing reduced flow or shorter run times, replacing the cartridge element restores filtration capacity without the expense of a new housing. The CX1200RE cartridge uses a reinforced polyester media and an extruded core to maximize surface area and water throughput. It is removable for routine maintenance and can be pressure washed inside and out to extend service life.

How does this cartridge improve my pool’s water clarity?

The Hayward CX1200RE captures larger particles at the surface while finer debris is trapped as the pleated media loads, producing progressively clearer water between cleanings. Its reinforced polyester fabric offers consistent pore structure and long-lasting performance, helping keep the pool circulation system efficient.

• 100 square feet of pleated filtration media for broad dirt-holding capacity
• Reinforced polyester resists chemical wear and holds shape during cleaning
• Extruded core design maintains high flow and reduces strain on the pump

How do I clean and maintain the replacement cartridge?

Routine maintenance is straightforward: remove the element, rinse it both inside and out with a garden hose, and inspect for tears or excessive wear. For heavier buildup, soak in a manufacturer-approved cleaner before rinsing; always let the cartridge dry fully before reinstalling if instructed by the cleaner’s directions.

• Pressure-wash pleats from top to bottom to dislodge trapped debris
• Check end caps and core for cracks or warping each service
• Replace when pleats are torn or cleaning no longer restores flow

Is this cartridge compatible with my filter and pool chemicals?

The CX1200RE is built to fit the StarClear Plus C1200 cartridge filter series and is compatible with commonly used pool sanitizers and maintenance chemicals. Hayward labels each cartridge end cap and wraps it in plastic to verify authenticity and ensure you receive a component that matches Hayward’s material specifications.

• Designed specifically for StarClear Plus C1200 housings
• Constructed to withstand standard pool chemicals without premature degradation
• Individually packaged and marked to confirm genuine Hayward replacement parts

What performance can I expect and when should I replace it?

Expect improved flow and longer filter cycles immediately after installation; real-world lifespan varies with pool usage, bather load, and debris type. Regular inspections every few weeks during the season will indicate when cleaning is insufficient and replacement is necessary—typically when flow does not recover after thorough rinsing and chemical cleaning.

• Restores original filter flow and efficiency when new
• Cleanable multiple times, extending service life before replacement
• Common replacement trigger: persistent low flow or damaged pleats

Who is this for: The Hayward CX1200RE cartridge is intended for pool owners, service technicians, and maintenance crews who use the StarClear Plus C1200 filter and need an OEM-quality replacement element. It’s ideal for both above-ground and in-ground pools that require 100 square feet of reliable pleated filtration and for anyone seeking a true Hayward part to preserve system performance and warranty compliance.
