Joel Leusink has been working in the ozone industry since 2003 performing engineering, sales and support for ozone applications in water treatment, agricultural, ground water remediation, and food processing applications.
Let’s go back to basics. Below is a simple read for the beginner:
What is ozone? Ozone is active or supercharged oxygen. It occurs naturally high in earth’s atmosphere and protects us from sun’s cancer causing UV rays. The ozone that we use is generated with eletrical and mechanical equipment. The chemical formula of ozone is O3.
What are some uses of ozone? Some common uses are: drinking water purification, wastewater treatment, deodorizing of smells, cooling tower water management, swimming pool water management, effluent treatment and industrial oxidation processes. Ozone Applications
What are some valuable properties of ozone? The most important property of ozone is disinfection. Ozone is therefore used for water treatment. Ozone also decolorizes (removal of color) and deodorizes (removal of odour).
How is ozone manufactured and can it be stored like oxygen?Ozone is manufactured from air or oxygen. There is very little or no ozone near earth’s surface. The ozone protective layer is miles above the earth and can not be accessed. Ozone cannot be stored like oxygen. Because of the very high reactivity of ozone, it is very unstable. Ozone decomposes to oxygen rapidly in minutes. Therefore ozone has to be generated at site and used immediately. Ozone Production link
Did You know?
Ozone is used in floriculture to decolorize roses to make them white.
Ozone gas is pumped into food and vegetable packing to protect themduring transportation.
Ozone is used to preserve Beer Hops to keep them fresh during storage.
Ozone is used for remediation after major fire accidents to remove the smell of fire. This is known as fire restoration.
Ozone is extensively used in Hydroponics (growing vegetables without soil).
There are nearly 2800 toxic chemicals in cigarette smoke and ozoneis effective against more than 80% of those chemicals that have beenidentified so far.
Has ozone been used to treat drinking water elsewhere? Ozone has been used in hundreds of water treatment plants around Europe (France, Germany, UK), USA, and in Asian countries (like China, Singapore). Ozone in drinking water
How long has ozone been known and used? Ozone has been known since 1800s and been used in little applications before the 80s but more extensively in the 90s. Today ozone use has become very common. History Of Ozone link
Does ozone has any odor? Ozone has a slightly sweet smell at very low concentrations but as the concentration increases, it becomes irritating. It has a fishy smell. During thunderstorms you get the pleasant smell of ozone. You get the smell of ozone in a Xerox shop and behind television sets.
Will ozone kill bacteria? Or will it stop bacteria multiplication? Ozone kills bacteria and is known to be the most effective bactericide on earth. There is no possibility of bacteria developing resistance with ozone.
What about virus? Ozone will deactivate virus by attacking the protein of the virus. Virus is a chemical entity and not a living organism. But it has DNAs that replicate fast. Ozone attacks this DNA. Ozone has been proven to act against SARS virus, against AIDS virus and also Swine fl u Virus. But Commercial applications have yet to begin for these applications.
We have recently started selling the MAX-Series of oxygen concentrators. This is a great addition to our oxygen concentrator line-up. We believe these units are a higher build-quality, at a lower cost, than the other units we have been selling, and have faster lead-times.
The MAX-Series oxygen concentrators are available in three sizes:
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.

is a very effective disinfectant and is effective against all viruses
and bacteria. Ozone
operates according the principle of oxidation. Ozone (O3) is
instable and will revert to oxygen (O2) on it’s own, or when it
contacts something it can oxidize. Living cells found in bacteria
and viruses are very susceptible to oxidation. As ozone enters
cells, it oxidizes (destroys) their components including the cell
wall. Once ozone has
entered, the process destroys all essential components (enzymes,
proteins, DNA, RNA). When the cellular membrane is damaged during
this process, the cell will fall apart. This is called lysis
— the disintegration of a cell by rupture of the cell wall or
membrane. From this point there is no recovery and the pathogen is
inactivated. Due to the direct oxidation ozone causes (loosing the
oxygen atom) there is greater energy to ozone oxidation vs other
commonly ozone is used dissolved into water. When dissolved in water
ozone increases the ORP (oxidation reduction potential) of the water,
all of the water is now a sanitizer with electrical potential for
pathogen inactivation through lysis. When the water (with sufficient
ozone levels) contacts a pathogen it will react with that pathogen
inactivity it. This is extremely efficient and effective.
can also be used in the ambient air in the gaseous form for
antimicrobial applications. Ozone in air is a spacial
consideration. The air is not charged as water is when ozone is
dissolved in water. Air simply has ozone in within it.
example. 0.1 ppm ozone is the safe limit for humans in air for
an 8 hour period of time. 20.0 ppm is a relatively high level
used in rooms at times for disinfection. This means 20 parts of
every 1 million parts of the air are ozone. This ozone
molecule needs to react with a pathogen cell to inactivate it. The
likely-hood of this in a short period of time is low.
ozone reverts back to oxygen quickly and frequently, longer
the exposure times
increase the odds of ozone reacting with the pathogen. Ozone
reverts back to oxygen faster (shorter half-life) as temperatures and
humidity increase. Therefore, higher
ozone levels, higher
temperatures, and higher humidity will
the opportunity for ozone to react with pathogens on surfaces.
Ozone levels used
for sanitation should be chosen based upon the goals and requirements
for this space, and the ambient conditions present. Reasonable
levels of 5-10 ppm are commonly used. Higher levels are also
possible. Keep in mind any natural rubber materials will be damaged
by ozone use at high levels over long periods of time. Therefore,
keep ozone levels and frequency of use reasonable.
documents on the use of ozone in air for antimicrobial uses. These
are great resources to use to ensure ozone is the right solution for
your application. Should you need more specific information let us
know, we will provide what we have.
A few options we
have for ozone sanitation in rooms are listed below. These systems
can also all be used in an HVAC system to maintain low levels of
ozone in a building for room air disinfection.
The S-200 ozone monitor will measure ozone as a handheld or with an optional remote sensor. Min/Max/Average ozone levels displayed on the screen along with current ozone levels.
0-100 ppm range (optional 0-1,000 or 0-10,000 ppm ranges)
0.0001 ppm resolution
For higher ozone levels with greater accuracy the UV-106L ozone analyzer can be used to measure and control ozone levels. The UV-106L includes built-in data-logging and accuracy to within 2% of reading. With a faster warm-up period, and greater accuracy the UV-106L is a great option for portable systems or systems that require greater accuracy.
Ozone levels in the room can be quickly converted safely back to oxygen via an ambient ozone destruct unit. The CDA-250 is a great device for this purpose. It flows 250 CFM air through the unit and destroys at least 90% of the ozone via a catalytic material in each pass. Using this device will lower ozone levels to a safe level quickly for faster turn-around time for your ozone disinfection room or chamber.
Gas gas can be an effective disinfectant in the gaseous form, but must be used safely and with proper caution. Should you have questions on this application, or any details, please contact our office.

1. Make certain all people, pets, and plants are out of area. Close all windows and doors.
2. Place the Ambient Ozone Generator on a shelf or tabletop as high as possible in the area to be treated.
3. Plug the power cord into a grounded, 3-prong outlet.
4. Set the timer to the desired length of time. Momentarily pressing the UP timer button for one second will increase the time setting by one minute at a time. Hold the button for 1 -3 seconds to change the time value by two minutes per second. Hold the button for longer than 3 seconds and the time setting will change in 20 minutes increments. The maximum time setting is 29:59 hours. After reaching the maximum time, the timer will wrap back to 00:00 and then continue increasing. When the time is being decreased and reaches 00:00, it will wrap to 29:59 and continue decreasing.
5. Select the desired power level: 25%; 50%; 75% 100%. The Ambient Ozone Generator always defaults to 100% when you plug it in. When the output level is set to 100%, the machine makes ozone continuously until the timer runs out or the OFF button is pressed. At other power level settings, the machine will produce ozone for the fraction of a minute the level is set at. For
example, if the output level is set to 75%, the machine will produce
ozone for 75% (45 seconds) of each minute. At 50%, ozone is generated
for 30 seconds of each minute, and at 25%, the ozone generation lasts
for 15 seconds of each minute. On any setting other than 100%, the ozone generator will be cycling the ozone ON and OFF.
6. Turn the unit on by pressing the ON button. Leave the area immediately.
7. When treatment is complete, ventilate the area completely until
all smell of ozone is gone. Do NOT allow people, pets, or plants back
into the area until all smell of ozone has dissipated.

At the time of writing, most major economies are entering into some form of lockdown, causing significant disruption to businesses and drastically changing the way we live our lives for the next few months.
Governments, Industry and Citizens are united in trying to slow the spread of COVID-19, to give health services time to prepare for the explosion in the demand for care. Sanitizing our homes, workplaces and public spaces is a key tactic in the fight against Coronavirus, to stop the spread of COVID-19. One method of sterilization is by using ozone. Ozone sterilization is commonly used in hospitals to sanitize equipment and significantly reduce or eliminate the spread of bacteria. Hence the question being asked is – “Can ozone sterilization kill the Coronavirus which causes the COVID-19 disease?”
blog post looks at the evidence and highlights the benefits of
sterilizing environments with ozone, as well as it’s associated risks.
OZONE STERILIZATION PROVEN TO KILL SARS-COV VIRUS
There are currently no examples in the public domain, of ozone sterilization being used to kill the current strain of Coronavirus, SARS-CoV-2
(technical name of the Coronavirus which causes the COVID-19 disease).
However, there are reasons to believe it would be effective:
As SARS-Cov-1 is also a member of the Coronavirus family, it is highly likely that ozone sterilization would be effective at killing SARS-CoV-2, the Coronavirus which causes the COVID-19 disease.
HOW DOES OZONE STERILIZATION KILL CORONAVIRUSES?
Coronaviruses are classified
as “enveloped viruses”, which
are typically more susceptible to “Physico-chemical challenges”. In
other words, they don’t like being exposed to ozone.
destroys this type of virus by breaking through the
outer shell into the core, resulting in damage to the viral RNA. Ozone
can also damage the outer shell of the virus in a process
called oxidation. Put simply, exposing Coronaviruses to sufficient ozone dose (ppm x time) can result in them being 99% damaged or destroyed.
WHAT ARE THE RISKS OF OZONE STERILIZATION?
even small amounts of ozone can be harmful. Symptoms include coughing,
shortness of breath, and aggravation of lung diseases like asthma. At
higher concentrations you can smell ozone, but it becomes harmful even
at lower doses. For that reason, many countries have set
an 8-hour exposure limit of 70 ppb (parts per billion) ozone. In the
EU the limit is set even lower. Ozone is one of six common pollutants
limited by the United States Environmental Protection Agency and other country’s Environmental regulators. Exposure to ozone in the workplace is controlled by the Occupational Safety and Health Administration and their counterparts around the world.
REDUCE THE RISK OF OZONE EXPOSURE BY MONITORING
ozone can sterilize coronavirus infected environments, residual ozone
could also cause respiratory issues for people who breathe it
in. To stop this from happening it is important to measure
and control indoor and outdoor levels of ozone after sterilization has
