Why is purified drinking water better?

Purified drinking water is simply better than any other alternative. Both in taste, smell and quality, it is a huge improvement from simply filtered or bottled water. 


A simple measurement of water quality is total dissolved solids (TDS), measured in mg/L, where the lowest valve indicates the cleanness for the water used.
