An aircraft has a ventilation system that employs a plurality of nozzles 96 positioned in a cavity between a sidewall 16, 18 of the aircraft cabin and a section of the aircraft fuselage 24, 26. The nozzles receive a supply of ventilation air and direct jets of air 104 from the nozzles, through the cavity and into the aircraft cabin. The jets of air produced by the nozzles create low-pressure areas 98 in the cavity. At least one return air opening 82 in the cabin sidewall communicates the low-pressure areas with the cabin interior, whereby the low pressure areas draw air 106 from the cabin interior into the cavity where the drawn air is entrained with the jets of air produced by the nozzles. Devices inside the cavity remove suspended impurities from the air drawn into the cavity. In this manner, the ventilation system filters or sanitizes the air drawn through the system.
