How does the PCO technology make the UV air purifiers effective?

Photocatalytic Oxidation (PCO) is an effective way to reduce many types of airborne bacteria, chemical contaminants, and odors. PCO is achieved when UV rays are focused on titanium dioxide (TiO2) filter. This process creates hydroxyl radicals and super-oxide ions, which are highly reactive electrons. Finally, 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, purifying the air
