Ozone, an allotrope of Oxygen with three atoms in a molecule,
is a wonder chemical form which has some
very unique properties.

It is 3,157 stronger as a disinfectant than chlorine
and 5.5 times stronger as an oxidant than pure oxygen.

Most delightful property of Ozone is that it is
very unstable having half life of
around 0 minutes only. After the stability period is over,
it quickly converts itself to nascent oxygen which has
strong oxidation properties as we know and being one of the most common element available in the atmosphere, this process of conversion does not contribute any hazaedous by products.

In one word, Ozone is the most environment friendly compound
if used with knowledge and proper technique.
