Built from reinforced polyester with a precision extruded core, this cartridge is aimed at people using Hayward Easy-Clear or Star Clear systems who want reliable dirt and debris trapping and straightforward maintenance. The review focuses on real-world use, ease of cleaning and compatibility with several Hayward cartridge models, so buyers know what to expect when swapping a tired element.

Key Features

• Direct fit compatibility: Designed to fit Hayward Easy-Clear and Star Clear models C400, 550, C120, C200 and C225 so replacement is straightforward for those systems.
• High filtration area: The element offers 55 sq ft of filtration area, which provides ample surface to trap larger particles and extend time between cleanings.

• Efficient water flow: The precision-engineered extruded core maintains good water flow while helping reduce energy cost by avoiding excessive pressure drop.
