In one example the body is a tubular body. An airflow pathway is provided through the tubular body defined between the first and second openings. A source of ultraviolet radiation is arranged to emit ultraviolet radiation into the interior space. A photocatalyst is arranged within the interior space and along the airflow pathway, and the ultraviolet radiation can be emitted onto at least a portion of the surface of the photocatalyst to activate the photocatalyst. In one example, the wall includes an aperture, and a cover is coupled to the body about the aperture and configured to enclose the source of ultraviolet radiation.
