Hayward CX225RE Replacement Cartridge Element - Reliable Pool

In this review the Hayward CX225RE replacement cartridge element is judged on fit, filtration performance and durability for owners of Hayward Micro Star-Clear C225 filters. The bottom line: this is a straightforward, genuine replacement cartridge that gives clear water and long filter cycles for most routine pool maintenance needs. It is best for pool owners who need an OEM-quality cartridge with 25 sq ft of filter area and expect easy installation and compatibility with Hayward chemicals. The review focuses on real-world use, weight, and whether it lives up to customer expectations for clarity and value.

Key Features

• Fits C225 filters: Designed specifically for the Hayward Micro Star-Clear model C225, so it slides in and seals like the original for predictable operation.
• 25 square foot media: The reinforced polyester element offers a large filtration area to trap dirt and reduce cleaning frequency.
• Durable construction: The reinforced polyester and extruded core are built to resist deformation and maintain water flow over typical cartridge cycles.
• Efficient flow design: Precision-engineered extruded core maintains strong water flow while helping keep energy use lower than a clogged or damaged element.
• Genuine Hayward packaging: Each element is individually wrapped with Hayward end caps for clear identification as a genuine replacement part.

Who It's For

The Hayward CX225RE is aimed at owners of pools equipped with the Micro Star-Clear C225 cartridge filter who want a genuine replacement that matches the original specifications for fit and filtration. It suits both above-ground and in-ground cartridge filter setups where a 25 sq ft element is appropriate and where users prefer a known-brand part compatible with Hayward chemicals.

It is less suitable for people seeking cheaper generic cartridges without brand labeling, or for those who need higher dirt-holding capacity than 25 sq ft can provide. If extreme longevity under heavy contamination is required, some users may prefer larger-capacity or different media types.

• Reinforced polyester media provides good water clarity and reliable filtration.
