Ozone gas is powerful and effective in removing odors, impurities and dangerous pathogens, and acts by exchanging electron charges from unstable ozone O3 with particles that come into contact with ozone to form oxygen O2. .. This process is particularly useful for purifying air and water and for killing bacteria and microorganisms that ozone comes into contact with. Ozone generators can often be used to generate ozone from oxygen molecules by exposing them to ultraviolet light. Ozone gas consists of oxygen molecules ionized by radiation to form a group O3 of three oxygen atoms, for example in a device, exposed to ultraviolet light to convert oxygen, air and oxygen to ozone gas. Can be produced using. However, while ozone gas is a powerful cleaning, disinfecting and sterilizing gas, it is not safe for the user to inhale the ozone gas until it is safely converted back to oxygen, so the ozone gas must be contained and controlled.
