Meet the Swimara Pro Series Pool Filter Cartridge, a mid-tier solution designed to replace essential filters in popular pool systems with a focus on reliable fit and thoughtful filtration performance. This cartridge is crafted to slot into Hayward Star-Clear Plus C1750/C1900 and related models, offering a straightforward drop-in install that aims for a secure, leak-free seal once the tank is open. The result is a practical, maintenance-friendly option for keeping pool water clear and inviting.

Advanced media for better surface coverage

The 3 oz Trilobal media uses triangular fibers that present more surface area than standard round fibers. In practice, this means more opportunities to trap fine debris while maintaining steady water flow. It sits between Swimara's Essential and Ultra flagship lines, providing a balanced mix of filtration precision and value.

• Significantly more surface area per cartridge for catching smaller particles (beyond visible debris).
• Designed to preserve flow even as particulates accumulate, helping you rinse and reuse efficiently.

Structure you can rely on

The anti-collapse design features rigid Trilobal fibers with a reinforced core. Pleats stay open and stable under pressure, reducing bounce and bunching. This translates to consistent cleaning performance and easier maintenance over time.

• 50% easier rinsing due to stable pleats and open channels.
• Longer service life from reduced collapse and channeling.

Specs and fit you can trust

This Swimara Pro-Grade cartridge covers a 175–200 sq ft filtration range. Key measurements align closely with the replacement targets, with an 8-15/16" outer diameter, 28-3/16" length, and 4" open hole. Always verify dimensions against your tank before ordering.

The Swimara Pro Series sits as a strong mid-tier option, combining precise filtration with solid value. It carries the reliability you expect from the Ultra line but at a more accessible price point, making it a compelling choice for consistent, dependable water clarity.
