The working principle of UV lampblack purifier:

When the lampblack molecules are irradiated by ultraviolet rays, the high-energy ultraviolet rays will break the chemical bonds in the molecules and form free radicals. Free radicals will react with other molecules, resulting in a series of chemical reactions, and eventually the fume will be broken down into water, carbon dioxide and other harmless substances.

Effect:

It reduces the pollution of oil fume to the atmosphere and reduces the harm to the human body.
