It depends. Usually, a sediment prefilter, carbon filter, ro membrane, and 2 DI cartridges. The first 2 protect the ro membrane. The last 3 purify the water.Just a question of curiosity... what are the 5 stages for a R/O system?

I don't think that is DI. It looks like a drinking machine that you would use at a local supermarket to fill water. So i assume the last 2 it lists are just for marketing purposes to say they have better RO waterDoes this make sense?![]()
The 5 stages that I usually see are: Sediment->Carbon->Carbon->RO->DI
I agree, that picture is of a drinking water machine at a grocer. RO, but not RODI. You would have to test it (at least for TDS) to determine how safe it is to use.
