"Ozone has been known for many decades to be the best and most efficient disinfectant".
Since the beginning of this pandemic, the disinfection of closed spaces, objects of daily use, among other things, were a great focus of attention in the search for a solution compatible with the presence of human beings.
Different national and international organizations have recommended countless measures, with the use of chemical products, such as alcohol, chlorine and many other substances, and the lack of accurate information has led many people to experience extremely harmful chemical combinations for health.
Ozone is a natural disinfectant that does not generate any type of chemical residue. It is an efficient and ecological solution for the elimination of pathogens, but since the beginning of the pandemic its effectiveness has been questioned both in relation to its effectiveness in inactivating the virus and because of its potential harmful to human health in high concentrations.
A study carried out, by the research group of Professor Takayuki Murata (virus / parasitology), at Fujita Health University (Japan), finally revealed that ozone gas in low concentrations is safe for the human body and inactivates the particles of the coronavirus.
According to research data, low ozone concentrations could be key to neutralizing the spread of the coronavirus in healthcare settings. Reuters reports that hospitals can be disinfected with the gas that neutralizes the coronavirus particles in the air, minimizing the spread of the virus.
In a lecture to the dam, scientists from Fujita Health University said they had succeeded in showing that ozone gas in concentrations of 0.05 to 0.1 parts per million (ppm) could kill the virus without causing harm to humans.
To demonstrate its effectiveness, the researchers used an ozone generator in a sealed chamber containing coronavirus (SARS-CoV-2) samples. The results revealed that the potency of the virus was reduced by more than 90% after being subjected to ozone for 10 hours.
"The transmission of the new coronavirus can be reduced by continuous low-concentration ozone treatment, even in environments where there are people, using this type of system," said lead researcher Takayuki Murata.
In previous studies, it has been seen that ozone gas has the effect of inactivating many pathogens and it was already known what it has effects on the new coronavirus. However, in a previously conducted experiment, ozone gas was used in a high concentration of 1.0 to 6.0 ppm and this raised concern to the scientific community due to its toxicity to the human body. This led them to carry out new experiments investigating the effectiveness of ozone in lower concentrations and they have finally shown that they are really effective.
A recent study at the Georgia Institute of Technology also showed that ozone can be effective in disinfecting gowns, goggles, and other personal protective equipment (PPE).
They are excellent news that experimentally demonstrate that this natural solution can help in the eradication of the virus in public environments, preventing its spread and consequently massive infections.
Lead Researcher Takayuki Murata points out that ozone machines should be used in closed public environments. Ozone generators have already been installed at Fujita Medical University Hospital to reduce infections in waiting areas and patient rooms.
This encourages us to encourage more and more the application of ozone in the most diverse types of businesses including medical facilities, clinics, pharmacies, supermarkets, greengrocers, butchers, fishmongers, stores of all kinds, gyms, shopping centers, in public transport, etc.
The research scientifically evidences the effectiveness of ozone in low concentrations against the virus and not harmful to human health, showing that it is possible to protect the population from outbreaks of Covid-19 with Ozone Generators.
