In an illustrative embodiment, an apparatus for treating air discharged to a passenger suite of an aircraft includes an enclosure that houses components for treating air passing through the enclosure and a detachable cover connected to the enclosure that provides access to the components. Air treatment components associated with air treatment flow paths within the enclosure include a blower with a fan that draws air through an air intake on the enclosure. An air duct is affixed to a discharge of the blower and directs the air discharged from the blower through an air treatment flow path that includes a scented cartridge with a scented medium that is absorbed into the air passing through the air duct. An air exhaust port is attached at a discharge end of the air duct that discharges the air conditioned by the scented cartridge through an air exhaust vent on the enclosure.
