The Pentek DFX-CB-20BB combines carbon block filtration and sediment reduction in one heavy-duty cartridge. Its dual-purpose Diamond Flow design helps reduce chlorine taste and odour while capturing sediment that can prematurely clog conventional carbon block filters. This provides excellent dirt-holding capacity, consistent filtration and a low pressure drop.
