If your water supply is chlorinated, your softener does nothing to change that, so an additional carbon filter stage before the membrane is recommended. Modern membranes are far less susceptible to chlorine degradation than they use to be, but it hasn't been totally eliminated, so why risk it?

My water is not chlorinated. It's well water. I guess I'm good. Thanks!
