Claim:
An aircraft air processing system comprising: a first channel connecting a passenger cabin in an aircraft to a secondary area in the aircraft; a second channel connecting the passenger cabin to the secondary area; an air supply conduit in the secondary area, the air supply conduit having an outlet; a nozzle section between the outlet and the passenger cabin, the nozzle section forming at least one nozzle for directing a first airflow from the outlet through the at least one nozzle into the passenger cabin, the at least one nozzle positioned with respect to the first channel such that the first airflow draws air from the passenger cabin into the secondary area through the second channel and recirculates the air drawn from the passenger cabin into the secondary area back to the passenger cabin through the first channel and through the at least one nozzle to form a second airflow that circulates between the passenger cabin and the secondary area through the first channel and the second channel; and a contaminant removal system in the secondary area and positioned in the second airflow to remove contaminants from the second airflow entering the secondary area from the passenger cabin through the second channel before the second airflow returns to the passenger cabin through the first channel and through the at least one nozzle.
