The ultraviolet photolysis oil fume purifier decomposes oxygen molecules in the air by using high-energy ultraviolet beams to generate free oxygen, that is, active oxygen. Because the positive and negative electrons carried by free oxygen are unbalanced, they need to combine with oxygen molecules to generate ozone. UV+O2→O-+O* (reactive oxygen species) O+O2→O3 (ozone). As we all know, ozone has a strong oxidation effect on organic matter, and reacts with malodorous gases and other molecules with irritating odor to achieve the effect of removing odor.

On the other hand, high-energy ultraviolet rays break the chemical bonds of malodorous gases and form free atoms or groups; At the same time, the generated ozone participates in the reaction process, so that the malodorous gas is finally cracked and oxidized to generate simple and stable compounds, such as CO2, H2O, SO2, N2, etc. So as to achieve the effect of purifying peculiar smell.
