Thanks to the many supporting scientific articles it is clear that ozone has a very good and effective sanitization power, but what is the real effect on COVID-19? Here we will see all the major scientific research on this thematic.
Thanks to its very strong oxidizing power, Ozone is recognized worldwide as one of the most valid solutions for the sanitization of objects and environments.
The effectiveness of the use of Ozone has been validated with the protocol of 07/31/1996 no. 2448 by the Italian Ministry of Health, which indicated it as “natural defense for the sterilization of environments contaminated by bacteria, viruses, spores, molds and mites and by the US FDA which certifies it in food processes.
However, the use of ozone involves risks that must be known and avoided for safe and effective use. It is in fact proved that ozone in high concentrations is harmful to human and animal health, for this reason it is essential to rely on a quality product which grants all the possible precautions to avoid risks.
OZONEXT with its products offers solutions that can be safely used by anyone, thanks to clear and simple warnings.

The extremely rapid spread of the SARS-CoV-2 has already resulted in more than 1 million reported deaths of coronavirus disease 2019 (COVID-19). The ability of infectious particles to persist on environmental surfaces is potentially considered a factor for viral spreading. Therefore, limiting viral diffusion in public environments should be achieved with correct disinfection of objects, tissues, and clothes. This study proves how two widespread disinfection systems, short-wavelength ultraviolet light (UV-C) and ozone (O3), are active in vitro on different commonly used materials. The development of devices equipped with UV-C, or ozone generators, may prevent the virus from spreading in public places.
In the experimental setting aimed at evaluating the ozone activity, the Ozonext Defender 10 (Cea S.p.A., Lecco, Italy) was adapted to be used inside a system composed of a plexiglass chamber containing the contaminated samples connected to an ozone detector, to monitor gas concentration (part per million, ppm) throughout all the experimental sessions.

The sanitization of surfaces and environments with ozone is also effective against the Sars-Cov-2 coronavirus. A further demonstration is provided by the study conducted by researchers from the School of Mechanical Engineering of Tel Aviv University in collaboration with the Department of Materials Engineering of the Azrieli College of Engineering in Jerusalem and the Faculty of Medicine of Bar Ilan University in Safed, Israel. The work provides scientific evidence of ozone efficacy in different areas of disinfection, this has filled the lack of specific tests against Sars-Cov-2.
“They were chosen on the basis of their abundance on common areas,” explain the study authors. Nickel and copper, for example, are used in electrical devices. Brass is a widely used material for decorations, musical instruments and jewelry. Stainless steel is often used in kitchen appliances, dishes and elevators, including doors and panels. Glass and aluminum alloys are also common materials”.

UNIVERSITY OF NARA - Japan
The research team of the Faculty of Medicine of the University of Nara in Japan, directed by Professor Hisakazu Yano of the Department of Microbiology and Infections Diseases and by director Kei Kasahara of the center for infectious diseases, carried out an experiment aimed at verifying the potential of ozone to sanitize environments and deactivate the Covid-19 virus. The experiment, repeated several times, was completely successful showing that ozone is able to deactivate and destroy the coronavirus. To communicate this good news, the Faculty of Medicine of the University of Nara issued a press release on 14 May 2020 in which it illustrated some details of the experimentation.
The one carried out in Nara University was the first worldwide test on the application of ozone for deactivation of COVID-19. This was accounced in 14 May 2020 opening a world of new opportunity in the fight against coronavirus.

According to Fujita Medical University, it has been reported that high-concentration “ozone gas” has the effect of suppressing the infectivity of the new coronavirus.
Professor Takayuki Murata of Fujita Medical University highlights: “We conducted an experiment to see the effect by generating low-concentration ozone gas. As a result, under the condition of 80% humidity, the amount of infectious virus was reduced to 4.6% after 10 hours without treatment”.
Based on the results of this experiment, Fujita Health University will install ozone generators in hospital waiting rooms and hospital rooms from next month.

The document presents an overview concerning “sanitization” intended as cleaning and disinfection in non healthcare settings taking into account scientific evidence of COVID-19 virus persistence on different surfaces and efficacy of cleaning and disinfection products for indoor environments. The document also considers the environmental impact and human health risk associated with the use of the products. It includes indications about textile disinfection treatment (to be carried out in indoor environments for clothing used in fitting or dressing rooms, upholstered furniture, curtains).
A glossary for terms used in the disinfection field, clarifying differences between terms such as disinfectant, sanitizing, environmental sanitizer and detergent for surfaces is also included.

GEORGIA INSTITUTE OF TECHNOLOGY - U.S.A.
Conducted by researchers at the Georgia Institute of Technology using two pathogens similar to the novel coronavirus, the study found that ozone can inactivate viruses on items such as Tyvek gowns, polycarbonate face shields, goggles, and respirator masks without damaging them — as long as they don’t include stapled-on elastic straps.
“Ozone is one of the friendliest and cleanest ways of deactivating viruses and killing most any pathogen,” said M.G. Finn, chair of Georgia Tech’s School of Chemistry and Biochemistry, who led the study. “It does not leave a residue; it’s easy to generate from atmospheric air, and it’s easy to use from an equipment perspective.”
“There was no reason to think it wouldn’t work, but we could find no examples of testing done on a variety of personal protective equipment,” Finn said. “We wanted to contribute to meeting the needs of hospitals and other healthcare organizations to show that this technique could work against pathogens similar to the coronavirus.”
