Why does the water ionizers filter leave some minerals in and not others?
The filter (depending on model) is a silver activated antibacterial carbon filter. It filters up to 0.01 microns, and according to John Archer’s book The Water You Drink filters out even all viruses. However it does not filter out the essential alkalizing minerals that are in solution. It’s important to understand, however, that our body’s calcium levels are only ever changed to a maximum of 15% by dietary supplement. The real loss is in the body leaching calcium from our bones to balance our excess acidity (70%). As your water ionizer does its job and relieves your body’s task of maintaining an alkaline balance, far less calcium would need to be leached from the bones. In other words, ionized water reduces the need for calcium supplements over and above normal dietary intake.
