About This Item
25 Sq. Ft. Replacement DE Filter Cartridge for Quad-Style Systems
The Unicel C-6900 is a precision-engineered replacement DE filter cartridge delivering 25 sq. ft. of filtration area via 42-pleat, 8 oz. DE filter fabric construction. Designed for quad-element DE filter systems, this individual cartridge restores your filter's performance when one element needs replacement — without pulling the full set.
⚠️ IMPORTANT: Full Filter Service Requires 4 Cartridges
Your Pentair Quad DE 100 requires 4 cartridges for a complete service. Replacing all cartridges at the same time ensures consistent flow, balanced filtration, and full filter efficiency. Add 4 units to your cart to complete your filter service.
