Steve, ammonia from chloramine goes through the carbon and RO membrane untouched. The DI is what takes care of the ammonia. Also, a person would have to have very low TDS out of the tap to have 0 ppm TDS after just RO.

Most people run their RO membrane until the water coming out of it is 10-15 ppm TDS. The DI will polish that up, extending the useful life of the RO membrane.
