- What Is TDS and Why Should You Care?
Total Dissolved Solids (TDS) is the total weight of all solids (minerals, salts, or metals) that are dissolved in a given volume of water, expressed in milligrams per liter (mg/L), or in parts per million (PPM)
The higher TDS level in the water, the more the probability of harmful contaminants that can pose health risks or hinder the absorption of water molecules on the cellular level
