*TDS (Total Dissolved Solids):

Determines the total amount of mobile charged ions, including minerals, salts, metals, cations or anions dissolved in water. It includes everything in the water except the pure water molecule (H2O) and suspended solids. The lower the TDS level, the purer the water.

Unit: ppm = part per million, 1 ppm = 1 mg/l, 1000 ppm = 1 ppt
