What are ozone generators?
Ozone Generators, also referred to as ozone machines, are ozone-generating devices that intentionally produce ozone gas. When sold as air purifiers to be used in indoor occupied spaces, they are marketed to be safe and effective (though these claims are generally false). This article discusses devices that produce ozone on purpose and not as a byproduct. Ionizers and electrostatic precipitators end up producing ozone as a byproduct as a result of their internal mechanisms.
You may have heard about ionizers. They used to be quite popular and were often used in homes to clean the air and eliminate odors. However, in the spring of 2005, Consumer Reports Magazine exposed the units as potentially doing more harm than good–it was found that several of these devices could produce harmful levels of ozone. Though ozone is a byproduct of these ionizers and tends to be produced at a lower level than ozone generators, the federal government began a stricter regulation process for any air purifier that produces ozone, whether intentionally or as a byproduct.
No federal agency has approved the use of ozone generators in occupied spaces, and the California Air Resources Board (CARB) has very strict regulations for air purifiers sold in California to make sure that harmful ozone levels are not being produced.
How do ozone generators work?
220V Ozone Generators produce ozone by breaking apart oxygen (O2) molecules into single atoms, which then attach to other oxygen molecules in the air to form ozone (O3). They accomplish this in one of two ways, according to the International Association of Certified Indoor Air Consultants (InterNACHI).
