4 . The air directing device of claim 2 , wherein the air reservoir defines a volume coupled to first, second, and third air channels, each of the channels coupled to a lower aperture and the air reservoir is further configured to direct the air to the blade nozzles through the first, second, and third lower apertures to output first, second, and third air curtains.

5 . The air directing device of claim 4 , wherein the air directing device is positionable above a row of seats in the aircraft, the row of seats comprising first, second, and third seats, and wherein upon positioning the air directing device over the row of seats: the first air curtain is output between at least the first and second seats, the second air curtain is output between at least the second and third seats, and the third air curtain is output between at least the third seat and a sidewall of the aircraft.

6 . The air directing device of claim 1 , wherein the first upper aperture has dimensions equal to or larger than dimensions of the portion of the PSU such that the first upper aperture is proportioned to receive the portion of the PSU comprising one or more air outlets.

7 . The air directing device of claim 1 , further comprising second and third upper apertures, each of the upper apertures dimensioned to be equal to or larger than air outlets of the PSU such that the first, second, and third upper apertures are proportioned to receive a portion of one or more air outlets, wherein the air reservoir is coupled to and receives air through the first, second, and third upper apertures.

8 . The air directing device of claim 7 , further comprising second and third lower apertures, each of the lower apertures comprising a sloped portion extending from the lower surface around an exterior edge of the respective lower aperture, wherein the air reservoir comprises first, second, and third air channels coupling the respective upper and lower apertures.

9 . An air directing device for interfacing with an airplane interior air system, the air directing device comprising:

a housing defining an interior volume comprising an air reservoir, the housing having an upper surface including a first upper aperture, a lower surface including a plurality of lower apertures, and sidewalls extending between the upper and lower surfaces, wherein the first upper aperture is proportioned to receive a portion of an aircraft overhead system comprising at least a passenger service unit (PSU) having gaspers that direct air to the air reservoir through the first upper aperture, and the air reservoir is fluidly coupled to the first upper aperture and the plurality of lower apertures, each of the plurality of lower apertures having an interior edge that includes a curved edge and an exterior edge that includes a sloped portion that forms a protrusion extending away from the lower surface, wherein each of the exterior edges forms a blade nozzle having a fixed position, and wherein the air reservoir is configured to, upon receiving air by the air reservoir through the first upper aperture, direct the air to the blade nozzle through the respective lower aperture to output a respective air curtain between passengers seated below the PSU; and

a vent mechanical interface projecting upward from the upper surface and configured to engage the upper surface with the PSU such that the first upper aperture receives a portion of the PSU.

10 . The air directing device of claim 9 , wherein the plurality of lower apertures includes four lower apertures, each of the four lower apertures comprising one of the blade nozzles.

11 . An air directing device for interfacing with an airplane interior air system, the air directing device comprising:

a housing defining an interior volume comprising an air reservoir, the housing having an upper surface including a first upper aperture, a lower surface including a first lower aperture and a second lower aperture, and sidewalls extending between the upper and lower surfaces, wherein the first upper aperture is proportioned to receive at least two gaspers of a passenger service unit (PSU) of an aircraft overhead system that direct air to the air reservoir through the first upper aperture, and the air reservoir is fluidly coupled to the first upper aperture and the first lower aperture, wherein the first and second lower apertures each have an interior edge that includes a curved edge, and an exterior edge that includes a sloped portion that forms a protrusion extending away from the lower surface, wherein the exterior edge of the first lower aperture forms a first blade nozzle having a fixed position and the exterior edge of the second lower aperture forms a second blade nozzle having a fixed position relative to the first blade nozzle, and wherein the air reservoir is configured to direct air to the first and second blade nozzles through the first and second lower apertures to output first and second air curtains between passengers seated below the PSU; and

a vent mechanical interface projecting upward from the upper surface.

12 . The air directing device of claim 11 , wherein the first upper aperture has dimensions equal to or larger than dimensions of the portion of the PSU such that the first upper aperture is proportioned to receive the portion of the PSU comprising one or more air outlets.

13 . The air directing device of claim 11 , further comprising a third lower aperture having an interior edge that includes a curved edge, and an exterior edge that includes a sloped portion that forms a protrusion extending away from the lower surface, wherein the exterior edge of the third lower aperture forms a blade nozzle having a fixed position.

14 . The air directing device of claim 13 , further comprising a fourth lower aperture having an interior edge that includes a curved edge, and an exterior edge that includes a sloped portion that forms a protrusion extending away from the lower surface, wherein the exterior edge of the fourth lower aperture forms a blade nozzle having a fixed position.
