BASICS ABOUT OZONE Ozone (O₃) is a pungent gas with a high oxidizing power. Thanks to this peculiarity, Ozone is considered the strongest disinfectant occurring in nature, able to quickly eliminate odours and microorganisms such as bacteria, viruses, mold, germs, etc. Because of its short life, it cannot be stored in tanks but it must be produced on site. Ozone, in fact, is created by special generators using Oxygen present in the air. Therefore, it needs neither filters nor refills.
