High energy and high ozone ultraviolet beam is used to decompose oxygen molecules in the air to produce free oxygen, i.e. active oxygen. Due to the imbalance of positive and negative electrons carried by free oxygen, it is necessary to combine with oxygen molecules to produce ozone. It is well known that ozone has a strong oxidation effect on organic matters and has an immediate effect on the removal of organic gases and other pungent Odors.

After the organic gas has passed through the filters, the organic (Odor) gas is decomposed and oxidized by high-energy ultraviolet beam and ozone, so that the organic gas material can be degraded into low molecular compounds, water and carbon dioxide, and then discharged outdoor through the extraction outlet.

After a series of chemical reactions, chemicals such as hydrogen sulphide and methyl alcohol, can be oxidized in a short period of time. At the same time, oxygen ions can destroy the living environment of bacteria in the air and reduce the concentration of indoor bacteria. Charged ions can adsorb suspended particles tens of times of their own weight and settle down by their own weight, so as to remove the suspended colloids in the air and purify the air.
