An air filtration device including a housing that includes an air intake and 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. The air filtration device also includes 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. The air filtration device also includes an air filter.

A plurality of air data may be collected by a sensor within a data center. The plurality of air data is received by a processor. At least a portion of the received plurality of air data corresponding to at least one zone within the data center may be determined to satisfy a threshold. Coordinates of a geographical location associated with the zone that includes the sensor may be transmitted to a robotic filter. The robotic filter can be dispatched to the transmitted geographic location to filter the zone.
