RO/DI System Recommendation

I'd consider looking at something with a 75 gpd membrane. Production may be a little slower than 100 gpd, but the rejection rate is generally better, so if you plan to add DI stage, that will more than likely last longer. This all depends on your incoming TDS though. RO membrane & DI media are the more expensive components of a water purification system, so you want to maximize the quality there.
