How TiO2 UV Photocatalytic Oxidation Works
Photocatalytic oxidation is achieved when you combine UV light rays with a TiO2 coated filter. TiO2 refers to Titanium Oxide. This process creates hydroxyl radicals and super-oxide ions, which are highly reactive electrons.
These highly reactive electrons aggressively combine with other elements in the air, such as bacteria and VOCs. VOC is an acronym for Volatile Organic Compounds, which include harmful pollutants such as formaldehyde, ammonia and many other common contaminates released by building materials and household cleaners generally found in the home.
Once bound together, the chemical reaction takes place between the super-charged ion and the pollutant, effectively "oxidizing" (or burning) the pollutant. This breaks the pollutant down into harmless carbon dioxide and water molecules, making the air more purified.
