Air sanitation devices and systems

An air sanitation device having a central axis extending therethrough in a generally vertical direction, the air sanitation device comprising:

• a free-standing base section comprising one or more inlets configured to draw in air at a height that is within a breathing zone defined as being between approximately 4.5 feet above ground and approximately 7.2 feet above ground;
• a body section comprising one or more outlets configured to discharge air at a height that is greater than or equal to approximately 7 feet above ground, each of the one or more outlets configured to discharge air in a plurality of discharge directions, each of the plurality of discharge directions being at least partially radially outward from the central axis;
• an ultraviolet (UV) light source disposed in an interior of the air sanitation device;
• and
• an air movement device configured to move air into the base section via the one or more inlets, past the UV light source, and out of the body section via the one or more outlets, wherein the air sanitation device is configured to discharge sanitized air into a breathing zone extending between approximately 4.5 feet above ground level and approximately 7.2 feet above ground level to thereby displace non-sanitized from the breathing zone.
