CTA Membranes - Reverse Osmosis Systems
CTA membrane (CTA-18) removes Total Dissolved Solids to improve the taste and quality of water. Tap water is forced by pressure through a semi-permiable membrane while dissolved solids and particulates are left behind. The CTA membrane is chlorine tolerant and is used correctly on municipally treated water or treated well water. Available on all our reverse osmosis units with a C18 code in the model number.

Meets or complies with NSF Standard 58.
