CTA Membranes are officially discontinued. It is easy to update your system to the superior TFC/TFM (thin film composite - thin film membrane) high performance menbranes. You will need to upgrade your sediment pre filter to a carbon pre filter. TFC-TFM membranes are chlorine intolerant and require a carbon pre filter or KDF pre filter to remove the chlorine prior to contact with the membrane. Then chose your desired membrane GPD rate and matching flow restrictor. That's it. For more on upgrading your CTA (cellulose triacetate) membrane see Membrane Upgrading.
