Ozone is a form of Oxygen.
Like oxygen, ozone is also a gas. It is that fresh
clean smell that you find at high altitudes and
after thunderstorms. Ozone is therefore named after
the Greek word Ozein, to smell. Ozone is present
all around us in the air that we breathe. It protects
us from harmful sunlight.
Because Ozone is also a powerful oxidising agent, it
has been used widely for the past 40 years to purify
water systems and the water you drink.
