POOLPURE C500 Pool Cartridge Filter for Hayward CX500-RE — 19.75" x 7" 50-Micron Trilobal Media, Lightweight

The POOLPURE C500 is a lightweight, high-efficiency replacement cartridge filter engineered to restore filtration performance for Hayward CX500-RE and compatible systems.

If your pool or spa is not clearing as quickly as it should, swapping in a fresh filter cartridge can make a dramatic difference. The POOLPURE C500 offers a modern trilobal-fiber media, reinforced end caps and a strengthened core in a compact, easy-to-handle package. Designed as an aftermarket replacement, it fits several popular cartridge models so you can get your system back to peak performance without the expense of an OEM part.

How does the C500 improve water clarity?

The filter uses a three-lobed (trilobal) fiber structure that increases surface area and traps finer particles than standard fabrics. Combined with a 50-micron fine-filtration layer, it captures dust, hair, silt and organic debris to help pools stay clearer between cleanings.

• Trilobal fiber gives more capture area than flat fibers.
• 50-micron layer removes very fine suspended particles.
• Dirt-lock design helps debris release during rinsing.

Will this cartridge fit my existing filter system?

The C500 is sized to match common replacement part dimensions used across multiple brands, making it a drop-in alternative for many cartridge housings. Confirm length and openings before purchase: this cartridge measures approximately 19 3/4" long with 3" open top and bottom ports.

• Length: 19 3/4"; outer diameter: 7"; top and bottom 3" openings.
• Compatible with Hayward CX500-RE and several cross-reference models.
• Designed as a compatible aftermarket replacement, not an OEM part.

How easy is it to handle, clean, and reinstall?

At roughly 1.0 lb, the POOLPURE C500 is significantly lighter than many traditional cartridges, which simplifies removal and reinstallation. Its dirt-locking fabric releases trapped debris quickly when rinsed, reducing scrubbing and water usage during maintenance.

• Ultra-lightweight design for easier lifting and positioning.
• Rinse-cleanable material speeds maintenance cycles.
• Durable construction resists tears for repeated use.

How durable and safe is this replacement cartridge?

Constructed from thickened polyester filter fabric with reinforced ABS end caps and an integrated core, the C500 is built for extended service life. It meets NSF/ANSI 50 safety standards for pool and spa components, ensuring material suitability for prolonged water contact.

• 4 oz. thickened polyester fabric and reinforced end caps.
• Integrated core design reduces deformation under flow.
• Tested to NSF/ANSI 50 material safety standards.
