| * The amount of soluble solids that are dissolved in one liter of water is measured by TDS (Total Dissolved Solids). Generally speaking, the more soluble solids that are dissolved in water and the higher the TDS value, the less pure the water is. As a result, one benchmark for measuring the water's cleanliness is the TDS value. | * The amount of soluble solids that are dissolved in one liter of water is measured by TDS (Total Dissolved Solids).
