REVERSE OSMOSIS ST-34ALK GAC COCONUT CARBON POST FILTER (STAGE 5)
Stage 5: ST-34ALK GAC Coconut Carbon/Alkalising Post Filter – Replace every 12 Months -NSF 42 /61
Extremely high-grade coconut carbon cartridge for maximum extraction of taste or odour issues. Final calcite (CaCO³) stage to raise the pH of the acidic RO water to a balanced state. The trace amount of calcium used is enough to neutralise the water, but not so much as to create calcium hardness issues in the water.
