Why Tersano SAO?
Stabilised Aqueous Ozone (SAO) is a proven altered water technology that replaces traditional cleaning chemicals and sanitisers.  This system is water in - SAO out. Unlike other altered water technology systems, the Tersano iClean mini and SAO Tersano unit, does not require any added salts and is non-corrosive. It leaves no residue behind and has proven superior cleaning, sanistising and deodourizing performance.
The iClean mini is GECA approved, which means that the Green Building Council of Australia recognise it for Green Star ratings and for the new WELL building standards. It is HACCP and NSF approved as a no rinse sanitiser in food areas and most recently as a food wash.

**Pending approval from the Ministry of Primary Industries (MPI) - Maintenance Compounds for both Dairy and Food grade use**

There are many gyms, aged care facilities, commercial buildings, universities, schools, hospitals, shopping centres, fast food outlets, hotels and other facilities around the world currently using this system.  We are now striving to increase where Tersano is currently used in New Zealand and to have this amazing system which is non toxic and chemical free, into more homes and businesses throughout New Zealand.


The Tersano system has the ability to significantly reduce your carbon/chemical footprint and reduce cleaning costs.
The patented SAO dispenser infuses cold tap water with ozone to create safe, high-performing stabilized aqueous ozone (SAO).

Benefits of SAO:


** We are pleased to announce that Tersano’s SAO solution was effective in eliminating >99.99% (>4-log) of all four (4) enveloped viruses with a one minute dwell time. Please see our updated Pathogen Summary**  See Tersano's formal announcment - click on PDF icon

  •  Eliminates germs, odours, stains, mould, and mildew

  •  Quickly kills viruses and bacteria including E.coli, Salmonella, MRSA and more *

  •  Safe and effective with no toxins, carcinogens, or chemical residue

  •  Converts safely back to tap water and oxygen

*Kills 99.999% of Escherichia Coli and Staphylococcus Aureus within a 60-second contact time.

1. Inside the SAO unit, oxygen from the air is safely turned into ozone then infused into ordinary tap water

2. The ozone is attracted to germs, stains and bacteria

3. Harmless to people, the ozone quickly attacks and eliminates contaminants it comes in contact with

4. Only pure oxygen and water remain after the ozone cleans and sanitizes.

Ordinary aqueous ozone is produced by using electricity to add an extra oxygen molecule to O2, creating O3.


This O3 is then infused into cold tap water to create safe aqueous ozone able to clean and sanitize for up to 24 hours. 



Certified Safe

SAO has been certified safe by the top regulatory bodies around the world and is safe for use in the most sensitive environments. From governmental bodies to independent test laboratories and sustainability organisations, stabilised aqueous ozone is a safe, sustainable alternative to traditional chemical cleaners and sanitisers.
