See my post (#3) above.
Basically 5 microns sediment-5 microns Carbon- CR SPOTLESS DI resin Cartridge. The main reason, I am running only 1 DI Cartridge because I don't use a lot of DI water and the resin supposedly only lasted 1 year.
I might try to go down to 1 microns filters and also do the RV Mod for the DI Resin when i am ready for filters change.
