CTA (cellulose triacetate) membranes have been being replaced by newer technology TFC (thin film composite) membranes. TFC RO Membranes cannot be exposed to chlorine as it will destroy the membrane and therefore they use a carbon prefilter to remove the chlorine prior to reaching the membrane. While we do offer replacement CTA membranes we recommend that you update your system to a current TFC membrane.
