Aqueous Ozone v Chemicals: Which is better at killing viruses and bacteria?

What is more effective at killing harmful viruses and bacteria – Stabilised Aqueous Ozone (SAO™) or cleaning chemicals? We have taken a look at the official lab reports to find the answer.

Firstly, what is SAO™?

Stabilised Aqueous Ozone (SAO™) is a highly effective cleaner, sanitiser and deodoriser made entirely from natural elements. It is one hundred percent toxic-free and proven to be much safer for people and the planet. Unlike toxic chemicals, you are able to spray SAO™ cleaning solution safely into the air and around people, killing airborne pathogens – something that would be just too dangerous to do with cleaning chemicals. SAO™ is created is by using volts of electricity, which are injected into normal tap water, splitting the oxygen atoms in the water and turning it from o2 into o3. Importantly, the stabiliser cartridge enables Aqueous Ozone to stay in this form for up to 24 hours which is unlike any other system on the market, hence the name ‘Stabilised’ Aqueous Ozone. Whilst in its o3 state, Aqueous Ozone is able to kill up to 99.999% of harmful bacteria and viruses, including Rotavirus, Hepatitus A, Influenza and more.

Can SAO™ kill bacteria as effectively as chemicals?

The short answer to this question is, yes – absolutely. SAO™ has been proven to be just as, if not more effective than standard cleaning chemicals. In fact, reports by Tersano state that SAO™ is 3000 times faster and stronger than bleach and chlorine-based cleaners, without the hazardous or toxic chemicals. SAO™ is also scientifically proven to kill an extensive list of bacteria and viruses, including some of the toughest ones to kill.

Why ‘dwell times’ are an important factor in SAO™ vs Chemicals

An important consideration when determining the effectiveness of SAO™ compared to cleaning chemicals is knowing the ‘dwell times’, or ‘kill times’ of each cleaning solution. Dwell times refers to the length of time you must wait between spraying your solution onto the surface before wiping it away, ensuring that enough time has passed to kill harmful bacteria. Dwell times can range from working instantaneously to requiring 10 minutes on the surface, depending on the bacteria that needs to be killed and the cleaning solution used. That’s why it’s important to know what the dwell time of your product is to ensure all harmful viruses and bacteria are effectively killed.

What are the dwell times of SAO™ and cleaning chemicals?

Testing by Tersano reveals that SAO™ is able to destroy various bacteria at a rate of 0-30 seconds (depending on the bacteria type). This means that cleaning staff in most sectors are only required to wait a maximum of 30 seconds in between spraying their surfaces and wiping it down, making their cleaning routine faster, more efficient and more effective. By comparison, most well-known bleaches have a contact time (or dwell time) of 2-3 minutes* making the cleaning process much slower.

The importance of dwell times and concentration at this current time is of significant importance. It is not easy for companies to change dilution rates with cleaning chemicals due to the increase in health and safety risks on staff when concentration levels rise. With SAO™, staff and companies do not need to worry about adjusting dilution levels as SAO™ gives you the maximum amount at all times without the safety risks.

What these reports show

What the research above shows is that both chemicals and SAO™ are able to kill harmful bacteria and viruses, however with SAO™, you can use it with confidence, knowing that it is killing bacteria and viruses quickly and effectively without the need to adjust dilution rates or increase the risk of toxic chemicals around staff.
