How Ozone is ProducedOzone (O3) is often called "activated oxygen"; It contains 3 oxygen atoms, unlike the air we breathe, which has 2 oxygen atoms. Ozone has the second highest sterilizing efficacy in the world and is therefore widely used. It is used to permanently remove bacteria, viruses, odors and unwanted odors. It is interesting to note that ozone is close to nature and is most often created by lightning. As a result, after a storm, you can feel the pleasant "rain scent" that is the gift of nature. However, it is likely that most of the issues related to ozone are related to the ozone layer around the Earth. The ozone layer created by the sun's ultraviolet rays is important to us because it protects against the harmful ultraviolet rays.
