Is RO water equivalent to distilled water?
Distilled water is boiled, and the steam is then condensed for drinking water. Distilled water contains practically no minerals or dissolved solids, whereas RO water does contain trace amount of minerals and salts. Most people report RO as tasting better than distilled water, which can taste flat. Distillers use electricity, whereas ROs work on line pressure from the household plumbing (except for commercial and industrial RO systems, which use pumps).
