If chlorine
dioxide was used to purify tap water instead of chlorine, I would not need to filter it (then add back the minerals that filtering takes out)
The difference is explained here-

extract-
Chlorine dioxide (ClO2) is a neutral compound of chlorine in the +IV oxidation state. It disinfects by
oxidation; however, it does not chlorinate. It is a relatively small, volatile, and highly energetic
molecule, and a free radical even while in dilute aqueous solutions
Some water authorities do use chlorine
dioxide- ours doesn't
I have some which I can use in drop size quantities to purify any spring water I might collect.
The
mineral content of water is vital for a healthy metabolism.
