Stabilised Aqueous Ozone

How it works

How Stabilised Aqueous Ozone is created

Stabilised Aqueous Ozone, otherwise known as SAO™, cleans and sanitises by working to attack organic matter at a molecular level. It then breaks this matter down into smaller particles, before suspending them in solution. This is what makes SAO so powerful.

SAO™ has in fact exceeded Green Seal Standards (GS-37 and GS-53). These standards dictate that a product must pass a stringent test to show its cleaning abilities as an industrial sanitiser.

Step 1

Treating the water

Tap water is put into a stabilisation cartridge, where impurities and minerals are removed. Treating the water in this way enhances its cleaning qualities.

Step 2


Once injected with volts of electricity, the oxygen molecules within the water are split from O2 (oxygen) into O3 (ozone).

Step 3

Kill up to 99.999% of viruses and bacteria

It is in this stabilised state, i.e., Stabilised Aqueous Ozone, that the solution acts as a powerful cleaner, killing up to 99.999% of viruses and bacteria upon contact.

What is it?

What is SAO?

SAO™ is a powerful and effective cleaner, sanitiser and deodoriser. Made from just water, oxygen and electricity, it is proven to kill up to 99.999% of harmful bacteria and viruses. The solution is created by the Tersano Lotus Pro iClean Mini cleaning products.

At the push of a button, volts of electricity are infused with normal tap water, splitting the oxygen atoms from o2 into o3. Whilst in this o3 state, it becomes a highly powerful cleaner and sanitiser, clinging to germs, viruses and bacteria and destroying them upon contact.

Thanks to the stabiliser cartridge inside the Lotus Pro and iClean Mini, SAO™ is able to stay in its powerful cleaning state for up to 24 hours, after which is simply reverts back to normal tap water.

The benefits

Stabilised Aqueous Ozone (SAOTM) is a simple and sustainable way to clean, sanitise and deodorise facilities. Reducing chemical use by up to 90%, SAOTM can take care of most of the day-to-day cleaning tasks required in most businesses and facilities.

You’ll also benefit from a significant reduction in chemical and plastic waste, making this one of the most sustainable and safe cleaning products on the market. SAOTM requires no COSHH (Control of Substances Hazardous to Health) regulation either as the solution doesn’t contain any harmful substances.


Eco-friendly solution

With SAO we do not greenwash.


Safe for use with no COSHH required


On-demand solution, ready when you need it


Dramatically reduces the requirement of chemical cleaner and sanitiser


Up to 6,000 litres produced

Second cycle of deozonation and oxygenation enables a faster access to the disinfected area.


Extended lifetime of solution

A powerful and effective cleaning solution

What makes Stabilised Aqueous Ozone so powerful is its effectiveness when converted into O3.

O3 is a naturally unstable compound, which means that it always tries to revert to its normal form. It is this unstable nature that makes it one of the most effective natural cleaning solutions. Its molecules latch on to surrounding dirt and bacteria, killing up to 99.999% of all harmful contaminants before turning back into normal water (O2). Deadly to germs, but safe for people and the planet!

Proven highly effective for over 100 years

Whilst Tersano products offer something revolutionary, Aqueous Ozone is not a new technology. In fact, it has been nature’s most powerful cleaner and sanitiser for over a hundred years. More than 1000 water plants are currently using it to naturally treat and purify water without chemicals. It has also been used in Olympic swimming pools as well as the military.

Now, thanks to Tersano, it is also being used in commercial and residential settings all over the world. The Lotus® Pro and iClean Mini™ utilise the clever science behind Aqueous Ozone, creating Stabilised Aqueous Ozone, to provide a safe, eco-friendly and powerful cleaner and sanitiser.

Completely safe and harmless to people

Many people associate the word ‘ozone’ with harmful and dangerous gases. Stabilised Aqueous Ozone is different. It is 100% safe and harmless to people and has been certified safe by leading governing bodies across the world, including the FDA and Health Canada. It is also HACCP and Green Seal certified.
