There are four different options available, from 4-stage to 6-stage, so it will really depend on your budget, your water source, and how many gallons you need to make.

IV) My Take
I’ve owned an RO/DI unit for over five years now. In fact, it was one of the first purchases I made. To put it simply, it’s not a sexy item, but it’s the best money I’ve spent in the hobby.
I’ve never once had to lug buckets back and forth from my LFS. I’ve never once ran out of RO/DI water. I’ve never once worried that my water was anything less than 0 TDS.
