The ozone machine is very small but very powerful. We use our ozone machine with any jobs that are odor-related and fire restoration jobs. Ozone is 3 oxygen atoms. The machine creates silent corona discharge which causes the oxygen (02) molecule to separate and turn into single atoms. Later these single atoms attach themselves to the oxygen (02) molecules and form ozone (03). In summary, this all means when the oxygen molecule changes into ozone, the molecular compound is no longer the same and the odor molecules can't be present in the ozone (03) molecule. An ozone machine is a great tool that is used to treat odors issues. It is best to do extended research on ozone machines or contact a professional to make sure the machine is used in a safe manner.
