Carbon Filter Cartridges
Carbon cartridges effectively remove chlorine, chemicals, and taste and odours from the water supply, resulting in fresh great tasting water.
Sediment Filter Cartridges
Water softeners work using ion exchange. Man made resin beads that have a high affinity for both calcium and magnesium ions are pre-loaded with sodium ions. When hard minerals pass through the resin, the calcium and magnesium are attracted to the resin and the sodium is released. So its swapping one thing for another.
