  There are many kinds of Sterilizer products on the market, including chemical disinfection, high temperature disinfection, ultraviolet disinfection, and ozone disinfection.

  Ozone, the English name is ozone/trioxygen, is an allotrope of oxygen composed of three oxygen atoms. At room temperature, it is a colorless gas with a special smell. Its name comes from the Greek word "ozein (ὄζειν)" which means "smell/smell". Ozone molecules are highly reactive, highly oxidizing, very unstable, and easy to decompose. They will gradually decompose into oxygen at room temperature, and will be accelerated into oxygen due to the catalyst of light, heat, moisture, metals, metal oxides and gases. Ozone Sterilizer

  Ozone has very strong oxidizing properties. The sterilization and disinfection function of ozone relies on its strong oxidizing property. The oxygen atoms connected by single bonds in the ozone molecule are very unstable and easily break into oxygen atom radicals, and are easy to combine with other molecules, thereby destroying many organic molecules.

  

  Ozone is a broad-spectrum bactericide, which can kill microbial pathogens including fungi/molds, fungal spores, bacteria, bacterial spores, viruses, protists and so on. Ozone is a very complicated process for the sterilization and disinfection of microbial pathogens. Ozone can combine with many components in cells to destroy their structure and function-including proteins on cell membranes, unsaturated fatty acids, various enzymes, and peptides on cell membranes. Glycans, DNA or RNA inside pathogens, enzymes, bacterial fungal spores and viral capsid proteins, peptidoglycans, and enzymes, etc.,-thereby killing pathogenic microorganisms. In addition to the strong oxidizing property of the ozone molecule itself, the by-products such as ·OH, ·O2–, HO·3, etc. produced during the reaction of the ozone molecule also have a strong oxidizing property.

  Some literatures have shown that the use of ozone for Escherichia coli, Salmonella, Bacillus cereus, Bacillus subtilis, Bacillus megaterium, Listeria, Mycobacterium, Staphylococcus aureus, Legionella pneumophila, Pseudomonas fluorescens , Feichsin Sartorius, phage, tobacco mosaic virus, polio virus, rotavirus, herpes virus, hepatitis A virus, hepatitis B virus, Aspergillus fungus, SARS virus , HIV virus and other experiments on disinfection and inactivation have achieved very good results.

  For the deodorization function of ozone, some peculiar smells are released by molds or other microorganisms. When these microorganisms are killed, the peculiar smell is also removed. Some odors are volatile organic gas molecules in the air, and ozone also combines with these organic gas molecules to effectively destroy these odorous gas molecules, thereby achieving the purpose of deodorization.
