It is oxygen in its most active state and is an extremely potent oxidant that has been shown to posses broad spectrum antimicrobial activity. Ozone is not just another disinfectant.
Ozone is a true sterilant.
It has the ability to completely destroy not only bacteria, but also viruses, spores, fungus, mold, mildew, cysts, and many other contaminants while at the same time removing dissolved organic materials by oxidation. The ozone then travels through clear, ozone-resistant tubing with a diffuser on the end. By placing the diffuser in a container of water you will see the ozone gas escaping into the water. No separate oxygen tank is needed to produce ozone in this manner. The strong distinctive smell verifies the presence of ozone.
