For maximum contaminant removal and long membrane life, the sediment and carbon pre-filters must be changed at 6-month intervals. If your water contains a great deal of sediment or chlorine, the pre-filters might have to be changed at more frequent intervals to maintain an adequate production rate. A main function of the Carbon Block pre-filter is chlorine removal to protect the TFC membrane from damage. Carbon filters have a finite capacity for removing chlorine, and the lifetime will depend on the level of chlorine in the water and the amount processed.
Replacement Carbon Block Pre-Filters remove chlorine, organic chemicals and chemicals that contribute to taste and odor. These filters act as almost absolute-rated sediment filters. They are much more efficient than the granulated carbon filters because there is no channeling or bypassing of fluids. They also have higher adsorptive efficiency and higher turbidity reduction than granular filters.
