1. An air purification system comprising:

  • an air purification apparatus that includes(a) an air inlet,(b) an air outlet for expelling air in a target direction into a region, wherein the air outlet includes an adjustment mechanism arranged to adjust said target direction in response to a target direction adjustment signal for aiming the air outlet at the face of a person in said region,(c) at least one pollutant removal structure disposed in between the air inlet and the air outlet, and(d) an air displacement apparatus for displacing air from the air inlet to the air outlet through the at least one pollutant removal structure;

    a breathing sensor adapted to determine a breathing parameter of the person, wherein the breathing parameter comprises at least an inhalation or an exhalation phase of a breathing cycle of the person at which the air outlet is aimed, wherein the air purification apparatus is configured to expel said air via the air outlet as a function of said breathing parameter; and

    a controller coupled to the air outlet and/or the air displacement apparatus, wherein responsive to the breathing parameter determined via the breathing sensor, the controller is arranged to increase an air flow rate and/or reduce the air flow rate of air expelled in the target direction, further comprising a suction device including;

    a suction port arranged to capture air exhaled by the person, said suction port including (i) a suction device and (ii) at least one sensor including the breathing sensor adapted to determine the breathing parameter of the person arranged in said suction port, said at least one sensor being arranged to monitor an analyte of interest in the captured air exhaled by the person; and

    a monitoring device arranged to monitor vital signs of the person from sensor data provided by the at least one sensor as the breathing parameter, wherein the air purification apparatus is configured to expel said air as a function of the vital signs monitored by said monitoring device, wherein the at least one sensor is at least one of;

    an O2 sensor, a relative humidity sensor and a gas temperature sensor.
