Q 1. What makes our Ozone Generators better?

Our commercial grade Ozone generators produce up to 15gr/hr of Ozone gas. The incorporated specially designed high flow fan system ensures the Ozone gas is quickly and efficiently spread throughout the treatment zone. This ensures that we can deliver the correct concentration and spread of Ozone gas required to effectively disinfect the treatment area, in the shortest possible treatment cycle time.

Furthermore, if you are one of our rental service clients, our technical team come back at regular intervals (based on the hours of treatments you carry out per week), to swap out your machine with another Ozone generator that has been fully serviced, programmed and checked.

This gives you and your team total confidence that the Ozone generator you are using is always operating at peak performance and that you are thereby achieving the highest possible level of disinfection for your space. This means a happier and safer working environment for you, your staff and your clients.

Q 2. What is ozone disinfection?

Ozone disinfection is a method of using the ozonation reaction of ozone gas to sterilise bacteria, viruses and moulds both on surface and airborne.

It is the use of specific concentrations of Ozone (O³) gas produced by a powerful ozone generator in an enclosed space. When ozone reaches specific concentrations in the enclosed space (room, office space, shop, treatment rooms etc.), the gas kills bacteria and neutralises viruses on any surface that comes into contact with the gas. This includes all hard surfaces as well as carpets, curtains, fabrics, chairs, wall etc.

Ozone is produced in the Ozone generator by combining oxygen and electricity. At the end of the process, the Ozone (O³) gas simply reverts back to Oxygen (O²) and because the process does not use any chemical additives, ozonation does not leave toxic residues on surfaces or in the air. READ MORE

Q 3. How does ozone disinfection work?

The antipathogenic effects of ozone have been substantiated for several decades. Its killing action upon bacteria, viruses, fungi, and in many species of protozoa, serve as the basis for its increasing use in disinfecting municipal water supplies in cities worldwide.

Typically, viruses are small, independent particles, built of crystals and macromolecules. Unlike bacteria, they multiply only within the host cell. Ozone destroys viruses by diffusing through the protein coat into the nucleic acid core, resulting in damage of the viral RNA. At higher concentrations, ozone destroys the capsid or exterior protein shell by oxidation.

Numerous families of viruses including poliovirus I and 2, human rotaviruses, Norwalk virus, Parvoviruses, and Hepatitis A, B and non-A non-B are among many others that are susceptible to the virucidal actions of ozone. Most research efforts on ozone’s virucidal effects have centred upon ozone’s propensity to break apart lipid molecules at sites of multiple bond configuration. Indeed, once the lipid envelope of the virus is fragmented, its DNA or RNA core cannot survive. Non-enveloped viruses (Adenoviridae, Picornaviridae, namely poliovirus, Coxsachie, Echovirus, Rhinovirus, Hepatitis A and E, and Reoviridae (Rotavirus), have also begun to be studied. Viruses that do not have an envelope are called “naked viruses.” They are constituted of a nucleic acid core (made of DNA or RNA) and a nucleic acid coat, or capsid, made of protein. Ozone, however, aside from its well-recognized action upon unsaturated lipids, can also interact with certain proteins and their constituents, namely amino acids.

Indeed, when ozone comes in contact with capsid proteins, protein hydroxides and protein hydroxides and protein hydroperoxides are formed. Viruses have no protections against oxidative stress. The enveloped viruses are usually more sensitive to physico-chemical challenges than are naked virions. Although ozone’s effects upon unsaturated lipids is one of its best documented biochemical action, ozone is known to interact with proteins, carbohydrates, and nucleic acids. The new coronavirus is an enveloped virus. READ MORE

Q 4. How effective is ozone disinfection?

Ozone is one of the most powerful disinfectants. It is 50 times more effective at disinfection compared to the most popular disinfectant – chlorine, and the effects of its action are visible 3,000 times faster.

Being in a gas form, it can penetrate almost all the corners of the space and therefore thoroughly disinfect the room. And experiments and tests show that the sterilising rate of ozone on various bacteria and viruses is 99.9%.

Using ozone to disinfect has the advantage that the ozone generated on-site reverts back to oxygen when the treatment cycle is completed.

Q 5. How long does it take ozone to kill bacteria?

Generally speaking it takes 15min of ozonation to kill most of the bacteria and viruses, and 30mins to kill all viruses and bacteria that have a presence in habitable area.

Ozone generators produce high volumes of Ozone gas to rapidly fill the space we are wanting to treat, however the space size effects how long it takes to disinfect an area. The disinfection cycle can last from a few minutes (for smaller spaces) to 2.5 hours for larger areas.

Q 6. Is ozone cleaning harmful?

The same chemical properties that allow high concentrations of ozone to react with organic material outside the body give it the ability to react with similar organic material that makes up the body, and potentially cause harmful health consequences. When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath and throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections. For our full service customers, our Ozone disinfection cycles are strictly conducted in closed off spaces where our trained operators have ensured there are no people, pets or plants present during treatment. For our rental customers, the disinfection cycles are designed for each individual client and application. This ensures the space is properly disinfected and that sufficient time is allocated so that the ozone gas can dissipate and revert back to oxygen thus ensuring no harmful exposure when people re-enter the space. Unlike traditional chemical cleaning procedures, once the cycle is complete, ozone does not leave any toxic air borne or surface residues.

Due to the instability of ozone, theoretically there should be zero presence of ozone gas 60min after the machine ceases it’s cycle.

Q 7. How many machines do I need for my space and what size machine is best?

This is dependant on your business needs and requirement for process time based on the size of the space.

We currently have 2 machines available. The OZO3 is capable of treating up to 750m3 of space in 150min.
For your normal size office space under 80m3, it only takes 10mins for OZO3 to generate desired concentration of ozone gas to achieve disinfection effect.
Then allow another 30min for ozone to deplete in the room.
Another larger machine we have, OZOair is capable of disinfecting a space up to 1500m3 in 150min.

Once you have completed and submitted the Assessment Form regarding your business and the space or spaces you wish to treat, our technical department will come back to you with the best package for you and your business.

Q 8. How often does an ozone machine need to be serviced?

Our high output ozone generators need to be checked and serviced regularly to ensure continued peak performance. These service intervals vary depending on the specific machine and the number of treatments. This regular servicing is part of our rental agreement. We establish the best interval with you and then one of our team members comes to you to swap out your ozone generator with a checked and fully serviced machine. This means you and your team have total peace of mind that your ozone generator and disinfection routine is always working efficiently.

Q 9. What’s the difference between ozone disinfection and disinfection surface cleaning?

Disinfection using Ozone gas is faster and far more efficient than traditional surface cleaning. The Ozone gas, just like oxygen, can completely fill the treatment space and covers all surfaces in the space. This includes inside keyboards, under desks, under arm rests on chairs, door handles, on walls, pens, and other objects in the space. Ozone also disinfects carpets, curtains and even seating fabrics. Most importantly ozone disinfection is achieved by using ozone gas (O³) which then reverts back to oxygen (O²) when the disinfection cycle is completed. This means so cleaning cloths, chemical sprays, plastic waste or toxic residues. Additionally ozone leaves no residue.

Q 10. Can I treat my premises on my own or does Ozone Disinfection do it for me?

Once you have completed and submitted an Assessment Form about the space or spaces you wish to treat, our technical department will come back to you to discuss the best treatment package and cycle for you.

We offer both Full Service Packages and Rental Packages. In the full service model, our trained staff come to your premises on an agreed interval to disinfect the area and then take the machine away. The rental package is where we leave the pre-programmed ozone generator with you. We train you on how to operate the generator and prepare the space. This means you can use the generator to disinfect the space without our operators. Our team are however always at your disposal for additional training or technical support.

Q 11. How can I advise my customers that my premises have been treated?

Once you become a registered Ozone Disinfection site, you will receive display cards for your reception, marketing material for your social media and communication, and a customised window sticker to show your staff and customers that you are using the Ozone disinfection system.

You will also have access to a specific webpage template that you can customise with your logo, explain the nature of your business, and add photos. This landing page also allows you to quickly update the date and time of the last treatment and that treatment data is then immediately available to anyone that scans the QR code that is specific to your business. That QR code is located on the window stickers we supply to you as part of your kit.

At Ozone Disinfection Australia, we want to ensure that your customers, staff and visitors know they are entering a space that is using the safest, most effective and environmentally friendly disinfection technology available to help you build trust and rebuild confidence.

Q 12. Why do I need air disinfection?

There are many airborne bacteria and viruses that can be harmful to human body and cause disease. Disinfecting the air can significantly reduce the transmission of respiratory disease and the common cold.

Our high output ozone generators disinfect the air as well as all the other surfaces and objects in the treatment area, thus resulting in a more complete disinfection cycle.

Q 13. How do I know there are no germs left after a treatment?

We can provide lab results showing the sterilisation rate of ozone gas on various bacteria and viruses.

Q 14. Does Ozone kill mould?

Yes, Ozone Disinfection kills mould spores, fungi and yeast.  If mould spores are disturbed, they can become airborne and, if inhaled, they can cause health problems.  That is why it is important to use Ozone to kill the mould before you attempt to clean up and remove the mould spores from surfaces.  For more information, please read more on our Mould Removal Page.

Q 15. Do you have any advice on how to clean dead mould spores off surfaces?

There are various effective ways to clean surfaces that have been effected by mould:

  • Diluted vinegar can be used to clean dead mould spores
  • Chlorine bleach makes an effective ingredient for removing mould stains.
  • Baking soda and water as a light scrub will remove the dead mould spores.
