In what is a major development, scientists in Japan have shown that low levels of ozone was 90% effective at destroying COVID-19.
This is a huge step forward as it shows that ozone at 0.05 to 0.1 ppm which is considered to be harmless to humans at these levels can be used to help protect people in communal areas like toilets, wash room, kitchens and waiting areas for example.
Unlike the high level ozone generators which can be harmful to humans and animals if exposed for long periods, the low level units that have been used for air purification for many years can also be used safely to help control the virus and reduce the risk of people being infected in these common areas.
Ozone, which is a gas that is heavier than air will sanitise the air as well as the surfaces that is touches giving multiple levels of protection.
Ozone should not be used as a replacement for manual cleaning but should be used as another layer of protection for customers and staff alike.
Ozone machines are being used in many locations and for many different uses.
Ozone is highly reactive and very effective at killing viruses, bacteria, pests, insects, molds, and more. In fact, it is a more powerful oxidizer than bleach or peroxide.
Larger Industrial-level ozone generators like the ones we supply can provide enough oxidising power to disinfect entire houses or buildings, and even sanitise surgery rooms to a pharmaceutical-grade level. However, low level machines can also be very useful in helping keep COVID-19 at bay.
TOKYO (Reuters) – Japanese researchers said on Wednesday that low concentrations of ozone can neutralise coronavirus particles, potentially providing a way for hospitals to disinfect examination rooms and waiting areas.
Scientists at Fujita Health University told a news conference they had proven that ozone gas in concentrations of 0.05 to 0.1 parts per million (ppm), levels considered harmless to humans, could kill the virus.
The experiment used an ozone generator in a sealed chamber with a sample of coronavirus. The potency of the virus declined by more than 90% when subjected to low level ozone for 10 hours.
“Transmission of the novel coronavirus may be reduced by continuous, low-concentration ozone treatment, even in environments where people are present, using this kind of system,” said lead researcher Takayuki Murata.
“We found it to be particularly effective in high-humidity conditions.”
Ozone, a type of oxygen molecule, is known to inactivate many pathogens, and previously experiments have shown that high concentrations, between 1-6 ppm, were effective against the coronavirus but potentially toxic to humans.
A recent study at the Georgia Institute of Technology showed that ozone may be effective in disinfecting gowns, goggles and other medical protective equipment.
Fujita Medical University Hospital, in Aichi prefecture central Japan, has installed ozone generators to reduce infection in waiting areas and patient rooms.
