What is Ozone

Ozone is Mother Nature’s most effective anti-microbial disinfectant

The chemical formula of ozone gas is O3. It is another form of oxygen (O2).

Ozone is basically active oxygen. It occurs naturally high in the earth’s atmosphere and protects us from the sun’s cancer-causing UV rays. This is the ozone layer that nature provides us for protection as many of us have come to know.


When lightning strikes, oxygen in the atmosphere is supercharged by the high voltage generated and ozone is produced. The “fresh scent” we often experience after a thunder and lightning storm is actually the natural smell of ozone.


Ozone is created when electrical energy splits an ordinary oxygen molecule (O2), starting a chemical reaction that results in ozone (O3).

Electrical energy splits O2 molecule into two O1 atoms. When the free O1atoms unite with other O2 molecules, ozone is created (O1) + (O2) = (O3)

The third oxygen atom is connected to the other two atoms by a weak link (see the dotted line in the diagram). This weak link makes the ozone molecule highly unstable, which is the key to its outstanding oxidising and sanitising prowess.

Because of its instability, the third oxygen atom can combine with organic and inorganic matter to destroy them through oxidisation. Only O2 molecule (the oxygen we breathe) is left in the air after the oxidisation process is over..

Why is ozone much better than chlorine?

Ozone is known to be the most effective anti-microbial disinfectant on earth. It disinfects and sterilises by killing all the bacteria and viruses it comes in contact with. Ozone is more than 100 times stronger, reacts 3,000 times faster* and much more effective in killing bacteria and viruses than chlorine. Although chlorine is widely used today for water treatment in most countries, it is also highly toxic and detrimental to the environment.

Unlike chlorine, ozone does not leave unwanted chemical residues in the water. Chlorine water treatment involves adding toxic chemicals into the water whereas Rogers England Ozone System merely adds ozone (a totally natural element) into the water. Ozone will eventually dissolve in the water as oxygen and dissipate into the air without any chemical residues whatsoever.

* Based on scientific comparative tests on the effect of chlorine and ozone on E. coli, the most common faecal pathogen that may be found in uncooked food and untreated water.

Is ozone fully proven, tested and recognised?

Yes. It is now being used to treat drinking water in hundreds of facilities in countries across the world such as France, Germany, UK, USA and Australia.

International bottled drinks companies have been using ozone for many years to disinfect water. Having previously used chlorine for the bottling process, they have found that ozone is by far the superior solution in providing consumers with safe, fresh-tasting drinks.

Due to its potent property as an anti-microbial disinfectant, ozone is also being used to sterilise operating theatres and medical wards in hospitals that are exposed to highly infectious diseases.
