    Ozone is a naturally occurring gas found in the ozone layer of the Earth's atmosphere, which rests between 10 km and 50 km above the surface of the planet. It is produced by both the sun's ultraviolet (UV) rays, and lightning strikes on Earth. In the ozone layer, the sun's harmful UV rays are filtered out before reaching ground level. If ozone ceased to exist, life on this planet would also cease to exist. 

Ozone (O3) is the same as oxygen (O2), but with one more oxygen molecule added in. In technical terms, ozone is known as a tri-atomic molecule comprised of three oxygen atoms, and is also described as "activated oxygen" or "super oxygen". It is an unstable blue gas, which means that in normal air conditions, ozone will cast off its third oxygen molecule, naturally converting into oxygen. Because of its unstable nature, ozone cannot be stored and transported like other industrial gases, and must therefore be produced on site.

       Ozone has a smell that is easy to recognize, and in low levels makes the air smell fresh. Most people can smell the presence of ozone in concentrations of about 0.01 ppm. It is the one of the strongest oxidizers known to exist (it works 3,125 times faster than chlorine), second only to fluorine. Because of its oxidizing properties, ozone does not simply cover up unpleasant smells, it safely and quickly destroys smells at the molecular level. Ozone has the ability to alter, decompose and/or neutralize materials that are toxic, without creating additional or by-product toxic compounds of its own.
