Taste/Odor Component

[EmilyB]

Does anyone use the last stage ? I found that I (after the DI at 0) registered TDS after the taste/odor component (AquaSafe) so I've never used it since. I have about five sitting around.

Can't one order all the components separately? I know SilverMax has some carbon, but I want the carbon block as well as the carbon filter. I don't want to get five more last stage that I never use. Any ideas?
