1. An air filtration device comprising:
a housing comprising an air intake;
a blower motor mounted within the housing, wherein when the blower motor is in operation, the blower motor generates an air flow from the air intake through an air duct extending vertically from the housing;
an air outlet at a distal end of the air duct, wherein the air outlet comprises at least one aperture, wherein when the blower motor is in operation, the air outlet discharges the air flow in a horizontal plane over an occupied zone from a region of the air duct having a vertical height that is less than or equal to twelve inches, wherein the region of the air duct for the air outlet is disposed at least thirty-six inches above the air intake, wherein the at least one aperture is configured to provide volumetric adjustment of the air flow; and
an air filter mounted within the housing between the air intake and the air outlet.
