(PC; Post Carbon Final polishing filter for taste and odor)
Post Activated Carbon Filter / T33 This carbon filter does an excellent job of "polishing" any dissolved solids that although unlikely, may have slipped through the 95% removal rate of the Reverse Osmosis Membrane and also through the DI Resin Bead Stage to give added assurance that you are getting the highest quality drinking water possible. The Final Polishing Filter also adds the mineral charcoal back into your water which helps to give the water a full bodied taste and also helps your body to detoxify.
