Pleatco Spa Filter Cartridge

Check the part number on your existing filter or consult your spa owner's manual. This model is a direct replacement for many standard 50 sq. ft. spa filters, including those from Unicel, Filbur, Waterway, and Custom Molded Products, provided the dimensions match your current housing.

You should measure the length and diameter of your current filter. This cartridge is 13.3125 inches long with a 5-inch diameter and a 2.125-inch port opening.

The Free Flow Core is designed to minimize flow restriction. By allowing water to pass through the center of the filter more efficiently, it reduces the strain on your spa's pump while maintaining effective filtration.

Smart Tracker is a time-stamping feature on the filter end cap that helps you keep track of when you installed the cartridge. You can write the installation date directly on the cap to ensure you stay on schedule with your maintenance and replacement intervals.

While cleaning frequency depends on usage, you should generally rinse the cartridge with a hose every few weeks to remove debris. For optimal performance and water clarity, most spa owners replace the cartridge entirely every 6 to 12 months.
