After the air is polluted, containing harmful inorganic gases, organic gases, and particulate matter. Such as ammonia (NH3), hydrogen sulfide (H2S), formaldehyde (HCHO), benzene (C6H6), carbon monoxide (CO), methane (CH4) and other ozone reactions with these contaminants for example as follows:


2NH3 + O3 = 3H2O + N2


C6H6 + 5O3 = 3H2O + 6CO2


2HCHO + 2O3 = 2H2O + 2CO2 + O2


CO + O3 = CO2 + O2


CH4 + 2O3 = CO2 + O2 + 2H20


The reaction described above ozone decomposition of harmful gases.
