ABSTRACT:
An air purifier has an air flow cavity bounded by cavity walls and a source of ultraviolet light emitting ultraviolet light within the cavity. The cavity walls have an ultraviolet light reflective coating. A plurality of photocatalytic particles are associated with the reflective coating. The photocatalytic particles are of a type which leads to production of oxygen and hydroxyl free radicals when illuminated with ultraviolet light in the presence of water.
