Ozone (O3) is a molecule consisting of three oxygen atoms. It occurs naturally in the environment. It is a pale blue gas with a distinctive pungent odor. It accounts for approximately 0.00001% of the ambient air.
Due to its active property of oxidizing other substances, nature continuously generates it through various electrochemical and electrostatic effects. In this way, it regulates the amount of mold, viruses, bacteria, and volatile organic compounds in the ambient air.
