The Journal of Hazardous Materials recently published a new paper on the use of ozone to inactive SARS-CoV-2, the virus responsible for COVID-19. The results aligned quite well with other work done on this topic with very comprehensive testing.
This study evaluated the inactivation of SARS-CoV-2, the virus responsible for COVID-19, by ozone using virus grown in cell culture media either dried on surfaces (plastic, glass, stainless steel, copper, and coupons of ambulance seat and floor) or suspended in liquid. Treatment in liquid reduced SARS-CoV-2 at a rate of 0.92 ± 0.11 log10-reduction per ozone CT dose(mg min/L); where CT is ozone concentration times exposure time. On surface, the synergistic effect of CT and relative humidity (RH) was key to virus inactivation; the rate varied from 0.01 to 0.27 log10-reduction per ozone CT value(g min/m3) as RH varied from 17% to 70%. Depletion of ozone by competitive reactions with the medium constituents, mass transfer limiting the penetration of ozone to the bulk of the medium, and occlusion of the virus in dried matrix were postulated as potential mechanisms that reduce ozone efficacy. RH70% was found plausible since it provided the highest disinfection rate while being below the critical RH that promotes mould growth in buildings. In conclusion, through careful choice of (CT, RH), gaseous ozone is effective against SARS-CoV-2 and our results are of significance to a growing field where ozone is applied to control the spread of COVID-19.
When using gaseous ozone relative humidity was also evaluated. As has been the case in other virus inactivation studies elevated humidity levels found higher rates of virus inactivation. In this test, humidity levels up to 70% were evaluated showing that realistic humidity levels can be used to achieve desired results but also leaving room for greater inactivation efficiencies with higher humidity levels.
The most useful information from this particular study was the effectiveness of ozone gas in inactivating the SARS-CoV-2 Virus on surfaces. Ozone was very effective in virus inactivation on both stainless steel and glass surfaces in a dried state.
While the global pandemic caused by COVID-19 continues the research on how to combat the SARS-CoV-2 virus continues. We expect this will not be the last research paper reflecting great results on the use of ozone to destroy viruses.

OMAHA, Neb. ( KMTV) — Every medical innovation has its unique origin story, and ozone therapy is no exception.
The ozone itself has been around as long as the Earth, but it was first synthesized in 1840 by German chemist Christian Friedrich Schonbein, who identified it as the source of the smell in the air after a lightning strike. Ozone is a highly reactive gas composed of three oxygen atoms, and it is both a natural and a human-made product that occurs in the Earth’s upper atmosphere, according to the Environmental Protection Agency.
During World War I, ozone was used as a topical application for infected wounds and an anti-inflammatory treatment, according to a clinical review of ozone therapy published by the Journal of Natural Science, Biology and Medicine.
“It is the most common medical ozone treatment today and is used by thousands of physicians worldwide,” according to the center.
How ozone therapy affects the body
Ozone therapy is an alternative treatment that practitioners use to take advantage of its various properties.
“Ozone has powerful anti-bacterial, anti-viral, anti-fungal properties, as well as the ability to neutralize toxins, boost the immune system and increase delivery of oxygen to all tissues,” according to Omaha Health Therapy Center.
Ozone therapy has been used to treat a variety of conditions:
Chronic bladder conditions
Upper respiratory infections
“In addition to killing viruses, destroying bacteria and eliminating fungus, ozone therapy supports many of the body’s basic functions,” according to Omaha Health Therapy Center. “One example of this would be activating red blood cell metabolism which leads to increased delivery of oxygen to the body and, because it helps to dilate constricted blood vessels, allows better blood flow. Ozone also increases the efficiency to the body’s own antioxidant system, helping to eliminate excess free radicals which are known to be the cause of many degenerative diseases.”
Ozone is arguably the most efficient tactic we can use to get rid of foul odors. This is because ozone has the ability to eradicate odors at their source. Ozone can do this because it is able to adjust the chemical makeup of the molecules that are creating the bad smell. Ozone is considered to be unstable because it is made up of three oxygen atoms. Eliminating bad smells with ozone occurs when the third oxygen atom attaches to the molecules that are creating the odor. This detachment/attachment onto the foul molecules change the molecular structure of whatever is creating the bad smell, and essentially changes them to non-smelling molecules. This is the process that makes ozone a necessity when traditional remedies like baking soda or store-bought cleaning supplies simply won’t do the trick.
There are a number of different instances where ozone use would be preferred because the smell you are dealing with is simply too stubborn. One of the most common instances where ozone could be used is in regard to getting rid of cigarette odors. Cigarette smells can be especially pesky for a couple reasons, such as the smell being absorbed into fabrics (carpet, car seats), and also because cigarettes have been smoked in an area for years on end without the area ever being properly cleaned. For applications like getting the smoke smell out of cars, it is important to note that ozone on its own will not be the answer to completely getting rid of the smell. You should also have your car’s carpet deep cleaned, as well the air conditioning system cleaned out. If you fail to also follow these steps, the smoke smell will continue to come back.
Dealing with pet odors is another time when ozone may be the right solution. Ozonating specific parts of your house where your pet typically resides will get rid of the smell that your pet causes. Another popular application is getting rid of the smell caused by mold and mildew. An important thing to remember is that if you have mold, the use of ozone will not get rid of the already present mold. Using ozone in this instance will get rid of the smell that the mold is causing, and could also help in stopping the growth of mold. However, ozone will not kill the mold itself.
When it comes to using ozone for odor removal, the ozone levels present will be above the exposure limits for humans (and pets for that matter). Because of this, please remember to take some safety precautions before you begin the process of oxidizing an area.
-Always remember to make sure that children and pets are out of the area and are unable to get into the area that you are oxidizing.
-Wait approximately 2-4 hours after the ozone generator is done running before returning to the area where it was used.
-In addition to human safety concerns, exposure to high enough ozone concentrations can also kill plants, cause damage to rubber, and discolor different materials, so make sure to take items out of the area you’re oxidizing to ensure they don’t get ruined.
There are many different options for ozone chambers. Many chambers will have an integrated turnkey system where ozone will be produced from the chamber itself. However, if you are looking for a more cost-effective option, or, you already have a chamber, room, or enclosure you want to control ozone levels inside of, building your own ozone chamber is a great alternative. This article will go over the different products necessary for assembling an ozone chamber, as well as some different specifications to take note of to make sure you get the products that will best fit your applications.

Ozone Generator – The most important component is the ozone generator to produce ozone for your ozone chamber!
Choose the ozone generator size and output, normally rated in g/hr (grams per hour), based upon the following factors
Size of your ozone chamber – larger chamber = more ozone demand
Level of ozone required inside your chamber, normally measured in ppm. Higher ozone levels desired will require larger ozone generators
Temperature of the chamber – higher temperatures will increase the ozone half-life and demand more ozone
Organic loading in the chamber – material in the chamber that will consume ozone due to natural organic loading should be considered
Ozone Monitor – An ozone monitor is required to measure ozone in the chamber and switch a relay in the ozone monitor to control the ozone levels. The ozone monitor will be located outside of the chamber with either a remote sensor, or small Teflon tubing inlet port placed inside the chamber to detect ozone levels.
Two main options are available to measure ozone
UV based ozone analyzer – pulls a sample of ozone gas from the chamber, passes through a UV lamp and measures ozone by determining how much ozone is absorbed by the UV lamp. This method allows for ozone detection accuracy up to 1%, and measurements from 0.001 ppm up to 10,000 ppm and even higher.
Remote mount sensor based ozone monitor – an ozone sensor is placed inside the chamber and wired to the main ozone monitor placed outside the chamber. This method allows for ozone detection accuracy ranging from 5 – 20% and measurement from 0.01 ppm up to 200 ppm reliably. These sensors are a lower price point than the UV analyzer and are normally used when cost is a concern.
The ozone measurement device must have a built-in relay that can be wired to the RCB-1 relay box that will turn the ozone generator ON/OFF. This relay should be easy to set and alter if necessary.
Relay Control – The relay control box has three components to it necessary for creating the ozone chamber. By looking at the image above, we can see the three different cords coming from the bottom of it (smaller white box on the far right side of the above image). Its far-left cord is simply connected to a wall outlet to supply power. The thinner, middle cord connects to the ozone monitor (far left, white/blue item) and then its far-right cord connects to the ozone generators power cord, and supplies power to the ozone generator. When it comes to which relay control box to use, Oxidation Technologies offers the RCB-1.
Ambient Ozone Sensor – We also highly recommend using either the C-30ZX Ozone Monitor, or the SM-70 Ozone Monitor to read for ozone in the air. This ensures that your environment is safe and free of ozone. Both of these monitors offer accurate ozone readings, compact designs, and low maintenance making them easy to use as well as extremely efficient.
How It Works
Looking at the diagrams below, ‘DIAGRAM 1’ shows the set-up for a custom ozone chamber when you are using one of the bench mount ozone analyzers, and then ‘DIAGRAM 2’ is showing the same basic scheme, but with a remote ozone sensor. However, the basic procedures are going to be the same, independent of which monitor set-up you decide to go with.
Following the diagrams below, we can see the procedures that will occur when your custom ozone chamber is working properly. First, using dry-air or oxygen as the feed-gas, your ozone generator will begin producing ozone for the chamber. Then, the ozone analyzer (or remote sensor) will read how much, in PPM, ozone is present in the chamber. The reading from the ozone analyzer will then be transferred to the RCB-1 relay control. Based on the reading given to the RCB-1, it will transfer a signal to the ozone generator to either continue producing ozone for the chamber, or to stop the ozone production.
The 5000BF Ozone Generator is capable of producing 7 g/hr of ozone from oxygen, or 1.8 g/hr of ozone from dry air. This generator is perfect for all kinds of applications, from personal use to industrial settings, as well as experimental testing. The compact design (6x12x17) and affordable pricing make it a great option for many different uses.

It is commonly said that the smell of ozone is present after a rain storm. This is true, and some great data I read this week explains this further. Read the whole article here.
From the article, it explains that ozone can be be detected BEFORE it rains.
Before it rains, as the wind begins to pick up and the clouds thicken or roll in, you may become aware of a noticeably fresh scent in the air. That sharp, clear aroma is ozone, a molecule made up of three oxygen atoms bonded together (O3) whose name comes from the Greek verb for smell, ozein. It’s the same gas we associate with the layer of our atmosphere that protects us from too much sunlight. As unsettled weather approaches, ozone is carried to the ground in strong downdrafts that, once they hit the earth, move horizontally as strong, gusty winds that precede the arrival of the rain. That wind, or “gust front,” and the smell of ozone that’s carried in it, reaches your nose a short time before the approaching rain arrives.
The act of rain falling from the sky further creates an extreme downdraft of air and pulls more ozone gas to the surface of the earth so that after a rain, the odor of ozone is still present.
It is important to note that while ozone is generated from lightening in a rain storm this is not the cause of the majority of ozone detected at ground level. So, the next time you “smell” rain, you can thank God for the gift of ozone and science for helping us understand it!

A paper was recently published by the Journal of Infection Diseases and Epidemiology that is promoting the use of ozone as a treatment for the Corona virus. Worth a read for sure.
Many viruses require reduced sulfhydryl groups for cell fu-sion and entry. Corona viruses, including SARS-CoV-2 (the cause of the condition now named coronavirus disease 2019 or COVID-19), are rich in cysteine, which residues must be intact for viral activity. Sulfhydryl groups are vulner-able to oxidation. Ozone therapy, a very inexpensive and safe modality may safely exploit this critical vulnerability in many viruses, inclusive of SARS-CoV-2
Recently ozone has gained a great deal of interest in the news. There is a role for a powerful disinfectant like ozone to play in the fight against COVID-19. Due to this, the use of ozone is finally gaining some worldwide attention.
For your reading pleasure we have compiled a few of the recent news stories. Have more? Send them to us, we’ll add to the list.
We are not endorsing any of the claims made in any of these articles. We are however celebrating the attention given to the power of ozone as a viable disinfectant. We hope this new awareness continues long after the COVID-19 crisis has subsided.
