post-filter stage, it polishes RO water by reducing unpleasant chlorine taste, odor, and residual impurities, ensuring clean and refreshing drinking water at the tap.
This 10-inch inline filter uses
premium coconut shell granular activated carbon (GAC), known for its excellent adsorption capabilities and long service life. It is commonly used in RO systems, refrigerator and ice maker lines, and under-sink filtration setups where final-stage taste and odor reduction is required.
