Ozone Sanitizing

Ozone is a well-known sanitizing agent.  Ozone sanitizes differently than chemical sanitizers.  The simple explanation is that ozone is an oxidizing agent.  Oxidation burns the thin outer membrane of bacteria and viruses hundreds of times in just minutes.  Without the outer membrane to protect it, the microbial threat quickly dies.  The basic concept is OXYGEN, which is a natural part of the normal atmosphere.  O2 is the breathable oxygen that will all need.  An ozone generator breaks apart the O2 and reforms it as O3 or ozone.

The third oxygen atom of the three-atom molecule is loose.  That oxygen atom breaks off when it contacts other material and oxidizes it.  For example, rust is oxidized iron.  So, if ozone can affect iron, it seems pretty simple to think that ozone will impact microbial life like bacteria and viruses.

Fortunately, it does not take a lot of ozone to kill bacteria and viruses.  In fact, recent studies detail that ozone levels of 5-6 ppm for 30-60 minutes will kill the coronavirus.  

The coronavirus is a fragile virus although quite infectious, and there are a variety of sanitizing products that will kill it. 

We are constantly asked, "What size ozone generator should I buy?"  That is a poorly-considered question.  Ozone generator size may be too much for a bathroom, and not nearly enough for an office building.  The real question is whether the ozone saturation level reaches 5-6 ppm during the treatment.  To do this, every professional or serious ozone treatment needs to use a quality ozone meter.

We spent a lot of time sorting through the junk on the market to find one that we liked.  We then added a "Data Logging" module that reports the real-time results on a screen or can be downloaded to a computer using a USB cable.  Frankly, if there is no ozone meter in use, there is no way to know if the treatment worked or not.

An ozone meter is useful for all kinds of ozone treatments.  Levels of 20 ppm may be required for a mold treatment.  This meter has a range of 0-100 ppm, and measures the levels to a tenth of a ppm.  We have found this ozone meter to be reliable, and the fact that it is self-calibrating allows unlimited uses without sending the meter in for servicing.

It is mandatory that no people or pets are in the treatment area, so how do we know if the ozone levels were 5-6 ppm or more?  

Our professional ozone meter has a red strobe and a loud beeping sound when the ozone is 5 ppm or more.  It goes off when the ozone level drops below 5 ppm.  So, if anyone is outside, they can see the red flashing light or hear the loud beeping.  They know that the ozone level is high enough to do a sanitizing treatment, and when the ozone levels have dropped to safer levels.
