Abstract
There is provided a moving sorbent filter within an air delivery device. The air delivery device has a housing having an air inlet and an air outlet, between the air inlet and the air outlet is located an air delivery fan having at least two rotating air moving means. The rotating air moving means intersect the flow of air between the air inlet and the air outlet and establish a higher pressure zone at the air outlet relative to the air inlet. The air delivery fan further comprising a moving porous sorbent filter formed of at least one sorbent filter element. The sorbent filter has at least one air passage allowing substantially unimpeded airflow into and through the sorbent filter.
