Air Ionization: Reality vs. Myth #1 - Ozone  
During one of my recent presentations of the Aerisa air purification technology, a client asked an interesting question, "Why do your odor control systems not create any significant ozone but I suspect that others do?"

I certainly can understand why this concern is raised as a result of inaccurate, misleading, or non-information given by others.  Further, improper configuration or operation of air ionization equipment have possibly led to detectable ozone (O3) readings above background. 

I want you to be certain that Aerisa air ionization systems are completely safe and are specifically configured to not create any increased O3 levels within the application area. As proof, see these videos from three of our installations.  (Note that some of these installations are over 5 years old.)

As you know, ozone can be an effective oxidizer of odorous gasses; however, relatively small concentrations may be irritating or worse.  Ozone is naturally occurring--background readings may be 0.01-0.04 ppm.  The OSHA standard for ozone is 0.10 ppm average over an 8-hour work shift--so, it doesn't take much more to be an issue.

We at Aerisa recognize that all electronic equipment creates some ozone--those that say otherwise are simply disingenuous.  However, if ionization equipment is manufactured correctly and the overall air purification system is engineered properly, there will be no increased levels of O3--again, see the videos.

One very important reason that Aerisa achieves superior results is that our ionizer units use voltages below 3000V to maximize ion production (e.g., O2+, O2-) and negate O3 formation. Legacy manufacturers (such as the former Bentax Sweden) use voltages at 5000V and above. The electron energies produced by these higher voltages will produce considerably higher levels of ozone.

Secondly, effective ionization system configuration necessarily includes an engineered ventilation design. Project-specific ion distribution ductwork and exhaust systems must be engineered properly. Aerisa wants to help you with this--we are ventilation experts with many years of HVAC experience. Simplistic systems with improper distribution or inappropriately recirculated air lead to poor results.
Aerisa will continue to lead the air ionization industry through successful installations as well as conveying truthful information about our technology.
