Claim:
An air distribution apparatus comprising: an air distribution vent that distributes air into a compartment, wherein the distribution of air into the compartment causes compartment air in the compartment to be drawn from the compartment into a secondary compartment; a first outlet to the compartment; a second outlet in an air supply conduit in the secondary compartment; a nozzle section between the second outlet and the compartment, the nozzle section forming at least one nozzle for directing a first airflow from the second outlet through the at least one nozzle into the compartment; and the at least one nozzle positioned relative to the first outlet and the second outlet and facing the compartment such that when the first airflow occurs from the first outlet that draws air from the compartment into the secondary compartment and recirculates the air drawn from the compartment into the secondary compartment back to the compartment and through the at least one nozzle, a second airflow occurs through the second outlet into the compartment causing the compartment air to be drawn from the compartment into the secondary compartment a contaminant removal system in the secondary compartment, wherein the compartment air drawn from the compartment is processed by the contaminant removal system to remove contaminants before being distributed back into the compartment by the air distribution vent.
