Water, though abundant, is certainly one of our most precious resources. RO/DI systems are designed to strip minerals and other dissolved solids out of your water supply to turn it into pure water, free of any contaminants. Such water is often referred to as RO/DI water or 0 TDS (total dissolved solids) water.
Not all RO/DI systems are made equal. The primary ways that they differ are in filtering capacity, the amount of pure water they can produce in a given amount of time, and in their waste ratio which is the amount of water it flushes to the amount of water it produces.
We only use and recommend one brand, Spectrapure, for all RO/DI producing needs. They have greatly specced out filtration systems, clear instructions, and top notch customer support.
