A new airflow device developed by UBC Okanagan engineers captures exhaled aerosols almost instantly, significantly reducing the risk of indoor pathogen transmission. The system uses a method called inductive sampling, or jet-sink airflow, which captures exhaled particles before they can spread into the space. Simulations during the 30-minute consultation showed that the new device reduces the likelihood of infection to 9.5%, whereas conventional personal ventilation systems have a risk of 47.6% and standard local ventilation up to 91%. With optimal placement of the device, only 10 particles out of 540,000 did not reach the other person during the first 15 minutes of exposure. Overall, the system removes up to 94% of airborne pathogens. The new approach also makes users comfortable for long-term use and better responds to the movement and interactions of people in the room, something traditional ventilation systems cannot do. The results were published in the journal Building and Environment and represent a significant advance in the protection against the transmission of respiratory diseases in confined spaces[2][4][5].
