What is TDS?
TDS means Total Dissolved Solids. It shows the amount of dissolved minerals, salts, and other solids present in water. A TDS meter gives the reading in ppm, which means parts per million.
A lower TDS value usually means fewer dissolved solids in water, while a higher value means more dissolved material is present. For RO and filtered water users, TDS testing is helpful for monitoring filter performance.
