Purozo has been doing everything we can to discover the effects of SAO™ against SARS-CoV-2, to keep our customers informed.
Over the past few weeks, Tersano has been conducting lab tests to learn more about Stabilised Aqueous Ozone’s (SAO™) effectiveness against different virus categories. Due to biosafety regulations however, it is not currently possible to directly test against the SARS-CoV-2 strain of coronavirus.
We have, however, been able to test the effectiveness of SAO™ on the globally approved surrogate virus for COVID-19, Murine Coronavirus/Murine Hepatitis Virus (MHV-3) and are pleased to announce that SAO™ has been proven to kill >99.99% (>4Log) of MHV-3 with a one minute dwell time!
About the test results
Following rigorous tests, which were conducted to the required standards and protocols EN 14476:2015, it was proven that SAO™ was effective in eliminating greater than >99.99% (>4-log) of the MHV-3 enveloped virus, with a one-minute dwell time.
While testing against MHV-3, the lab also tested against Influenza A Virus (H1N1), Measles Virus and Syncytial Respiratory Virus, all of which belong to the enveloped virus subcategory. Tersano’s SAO™ solution was as equally effective at eliminating greater than >99.99% (>4-log) of these viruses with the same one-minute dwell time as the MHV-3 virus.

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.

Why is testing against a surrogate virus important?
MHV is one of the only globally accepted surrogates for COVID-19, as stated here and by the World Health Organisation (WHO). This is important to note because it means that not only is MHV-3 in the same family as SARS-CoV-2, but it has an almost identical structure, as show in the diagram below.
Note that, the red box shows a phylogenetic tree of coronaviruses. Next to that tree, you can see the genome structures which make up each strain of coronavirus, of which the 2019-nCoV and MHV-A59 are most similar, and in fact almost identical.
