What is the TDS Water Test?
TDS is tested in water through special meters that detect particles. Your ZeroWater® TDS meter will show the number of solid particles per one million water particles (ppm). For example, a value of 60 ppm means that from one million particles there are 60 dissolved ions and the rest (999,940) are water molecules. 5-Stage water filters by ZeroWater® remove 99.6% of total dissolved solids in your drinking water.
