What is TDS and why should you care TDS = Total Dissolved Solids, which is any salt, metal, or mineral in the water. The lower the TDS level in the water, the more efficiently your body’s cells can use the water. Conversely, higher TDS levels can indicate water that is more difficult for your body to use and has more contaminants that can pose health risks.
