Why not Ozone?

Why not Ozone?

It is great in water applications but in air it is a different story.
Prominent research comes from the US EPA and the WHO (World Health Organisation) has found significant impact to human health when Ozone is introduced into our living space. 
If you look at Ozone products on the market . Ozone machines produce between 1000 to 10,000 times more ozone than is regarded safe in indoor air quality application.
Here are some links to the research.
  • US EPA 
    • has easy to read information about Ozone and how it is harmful to humans
    • says  "Manufacturers and vendors of ozone devices often use misleading terms to describe ozone. Terms such as "energized oxygen" or "pure air" suggest that ozone is a healthy kind of oxygen. Ozone is a toxic gas with vastly different chemical and toxicological properties from oxygen"  
    • Ozone basics paper  indicates
      • good ozone as "stratospheric ozone, good ozone occurs naturally in the upper atmosphere' and
      • bad ozone as "Tropospheric, or ground level ozone, is not emitted directly into the air, but is created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOC). This happens when pollutants emitted by cars, power plants, industrial boilers, refineries, chemical plants, and other sources chemically react in the presence of sunlight."
  • WHO
    • page 14  states "There is some evidence that long-term exposure to ozone may have chronic effects" and table 3 note says "Deaths attributable to ozone. Time-series studies indicate an increase in daily mortality in the range of 0.3–0.5% for every 10 µg/m3 increment in 8-hour ozone concentrations above an estimated baseline level of 70 µg/m3 ."
