In this study the separate and combined impact of the interaction of the free convection flow (FCF) with the flow of respiration and ventilation flow generated by personalized ventilation (PV) on the exposure to human bio-effluents was studied. Dressed breathing thermal manikin seated in front of desk was used to resemble human body with the FCF. The experiments were performed in a climatic chamber at 23 °C. CO2 was released at the armpits and N2O at the groins to simulate respective bio-effluents. The tracer gas concentration in the inhaled air was measured with gas analyzer with short response time. The invading PV flow with a center line speed of 0.4 m/s at the face of the manikin penetrated the FCF. The inhaled air was 90%-98% clean of bio-effluents. At 0.2 m/s the PV flow was less efficient in removing pollutants from the armpits than from the groins.
