  • Patent number: 8709341
    Abstract: An air purifying system includes one or more air permeable photocatalytic elements defining a core cavity having a sealed top end and an open bottom end. A sealed air flow path ensures that air travels from an outside of the core cavity, through the one or more photocatalytic elements, into the core cavity, to be expelled through the open bottom end. A UV radiation source disposed within the core cavity irradiates air travelling along the sealed flow path and an interior of the one or more photocatalytic elements. Each photocatalytic element is manufactured using a substrate, that is conductive of and transparent to UV radiation, coated with a photocatalyst. A non-photocatalytically active material is initially coated on the substrate and is then converted to a photocatalyst by calcination.
