Reduction the risk of airborne infection with mixing ventilation (mixing) and personalized ventilation (PV). Office room with 10 occupants working together for 8 hours. Reproductive number shows number of secondary infections that arise when a single infectious case is introduced into a population where everyone is susceptible.

Reduction of exhaled aerosols in a meeting room (20 m2, 50 m3) med 10 persons. Calculations according to Ref. [17]: Low pollution building, Category III - 3,46 ACH; Category II - 6,05 ACH; Category I - 8,46 ACH; Category III 3,46 ACH + source control (the 10 persons use headset with installed exhaust with 80% efficiency).
