Ozone contains 3 atoms of oxygen, compaired to the 2 atoms of oxygen which we breathe. This third oxygen atom makes ozone very reactive and it readily attaches itself to other molecules. When contaiminants such as odours, bacteria or virus come into contact with ozone, the ozone attacks the molecules, destroying them and the odour. This makes ozone a very effective sterilser.
Ozone generators work by drawing air through a pre-filter to capture large dust and dirt particules. The minute particles then pass through the system where oxygen is converted into ozone via the corona process. The ozone then passes through the machine where it works to remove odours, smoke and other contaminants in the air.
