Nitrate (NO3) comes into water supplies through the nitrogen cycle rather than via dissolved minerals. It is one of the major ions in natural waters. Most nitrate in drinking water is the result of contamination of groundwater supplies by septic systems, feedlots, and agricultural fertilizers. Nitrate is reduced to nitrite in the body. These cartridges contain a special nitrate-selective resin. Nitrate reduction is 90% to 95% and breakthrough is not affected by sulfate levels.
The catalog often lists the same model at several merchants — worth a price check before you buy.
