The Unicel C-7633 is a versatile 33 square foot replacement filter cartridge compatible with Purex CF-33, CF-66, and CF-100 pool and spa filter systems. Its pleated construction creates a generous filtration surface that traps dirt, debris, and waterborne contaminants while reducing hydraulic resistance on your pump to help prolong its operational life. Measuring 14 inches long with a 7-inch diameter, this cartridge is solidly built for dependable, ongoing use. CF-66 filter systems require two of these cartridges, while CF-100 systems need three, making the C-7633 a flexible solution across multiple Purex configurations.
