Ultra Pool Replacement Cartridges combine 3-in-1 performance technologies into one replacement cartridge. 

• PurePleat: helps avoid bunching and captures dirt in the outer edges for easier rinsing
• Point Bonded: fabric designed for uniformity and stability — plus excellent dirt capture
• Free Flow Core: creates maximum space for water to reach more of the fabric faster, reducing operating pressures on the system
