I found this:
What Chemicals do Reverse Osmosis and Distillation Remove/Reduce?
Reverse osmosis will generally remove any molecular compounds smaller in size than water molecules. Such compounds include salt, manganese, iron, fluoride, lead, and calcium (Binnie et al, 2002).
And of course the down-side:
Reverse osmosis, because it removes minerals according to physical size, is non-selective in its removal of dangerous and beneficial minerals.
The law cannot make a wicked person virtuous…God’s grace alone can accomplish such a thing.

Setting a good example is a far better way to spread ideals than through force of arms. Ron Paul
