What it does

This T33 coconut-shell granular activated carbon filter is designed as the final (post) stage in a countertop or under-sink RO system. After the RO membrane does the heavy lifting, this filter polishes the water — improving taste and odor and helping reduce any residual chlorine before the water reaches your glass.

It’s filled with premium coconut-shell GAC, known for strong adsorption and clean taste. NSF/ANSI 42 certified for chlorine, taste, and odor reduction. Ships with adapters for both 1/4″ and 3/8″ tubing.
