When your pool water won’t stay clear or your filter pressure rises too quickly, worn or torn DE grids are often the cause. The Unicel FS-2003 36 Sq Ft DE Filter Grid Set is a complete 8-piece replacement grid set designed to restore proper filtration performance in compatible DE pool filters. Built with high-quality Reemay® filtration fabric, these grids deliver superior dirt capture while maintaining strong water flow.
Replacing all grids at once ensures balanced filtration, consistent pressure, and longer filter cycles—helping your pool stay cleaner with less maintenance.
