Does Ozone Kill Coronavirus

Our office has received numerous calls about whether ozone kills the coronavirus.  It is well-known that ozone does kill pathogens (bacteria and viruses).  Ozone is a non-chemical solution that can be applied to treat large or small areas and it reaches all surfaces with a nominal treatment.  This does not mean there is no need to properly clean the area, but ozone can be an augment to a sanitizing program.

To directly answer the question, ozone has been proven to kill numerous types of viruses.  This includes previous versions of the coronavirus.  COVID-19 has proven to be a fragile virus that can be sanitized by washing your hands with soap and water.  There are a variety of product that kill COVID-19, but they are often chemically-based.  

So, we are relying on the several past versions of SARS, Bird, Flu, and MERS to support the belief that previous sanitizing methods will also sanitize the COVID-19 virus.  More testing is needed to confirm the efficacy of a proper ozone treatment on the COVID-19, but the early signs seem to favor ozone sanitizing for this virus. In light of the rampant onset of this new coronavirus, many groups are using ozone as a sanitizing process for face masks, clothing, and rooms to stay ahead of the crisis.  This includes medical groups, fire and police departments, and support groups trying to recycle masks and clothing by frontline workers. 

Unlike treating mold, pollutants, or heavy odors; killing pathogens does not require a strong dose of ozone.  Treatments of about an hour or two should be enough to kill bacteria and viruses on surfaces.

Short ozone treatments are therefore easy to apply.  Set the timer for an hour and spend a little time outside the house or building.  

Combine routine ozone treatments with proper cleaning and sanitizing already in place, handwashing, and controlling infection hotspots for maximum effect.

Cleaning cycles need to shorten and sanitize "High Touch Areas" very often.

Finally, we suggest applying a probiotic solution to the end of any cleaning process that will inhibit the reinfection of infectious pathogens.  The use of probiotics is not the same as killing germs with a sanitizer.  It is viewed as a prophylactic measure that can extend the protective measures to prevent the spread of disease.
