Ozone is effective in neutralizing Covid-19, reveals Japanese research

Ozone is known for its disinfectant properties and a new study confirmed its effectiveness in reducing the potency of the virus by up to 90%

Disinfection of spaces, everyday objects and surfaces has become one of the most sought after topics since the beginning of the Covid-19 pandemic.

Although the World Health Organization has issued different recommendations for disinfection that are based on ethyl alcohol, chlorine, and soap and water, the misinformation has led thousands of people to experiment with combining substances and chemicals that can cause harm to both health, as well as the objects and surfaces in question.

8 months after the first outbreak, the ozone joins the list of substances whose scientific evidence shows that effective to neutralize Covid-19, according to research by scientists at Fujita Health University in Aichi prefecture, Japan.

To test the effectiveness of ozone in deactivating SARS-CoV-2, the scientists put an ozone generator and coronavirus samples in a completely sealed chamber.

After the experiment, the research concluded that an ozone concentration between 0.05 and 0.1 parts per million units (ppm) is highly effective in lowering the potency of the virus by up to 90% when the particles are exposed to ozone for ten hours.

“The transmission of the new coronavirus can be reduced with continuous treatment with low-concentration ozone, even in environments where people are using this type of system,” explained the leader of the research, Takayuki Murata.

Although since the beginning of the pandemic there has been speculation about the effectiveness of ozone to disinfect cars, offices, buses and all kinds of environments, it is the first scientific evidence confirming this effect.

However, despite its efficacy as a disinfectant, ozone in high concentrations can be harmful to health and therefore, it is completely inadvisable to use it beyond industrial purposes, whose most common applications are carried out in public swimming pools or wastewater.

The finding could help to devise ventilation systems or implement generating machines in public spaces where the virus circulates and help reduce mass infections.

The results of this investigation have no relation to the ozone therapy, an alternative treatment lacking scientific evidence and it has caused controversy in the medical community around the world, since the main health institutions in the world consider it a toxic gas, whose beneficial effects in low concentrations when introduced into the body combined with oxygen are not confirmed.
