About the TDS

TDS is the short name of the Total Dissolved Solids， TDS-3 is the total weight of all solids, including of the minerals, salts, metals, dissolved in a given volume liter(mg/L), or in parts per million(ppm).

The lower TDS level in the water, the more efficiently for human body's cell.

The higher TDS level in the water, the greater harmful contaminats for body.
