Air hygiene on wheels

Purpose and goal For many infectious diseases, the transmission of infection between people takes place through aerosols containing the infectious agents. The often cramped spaces in buses and taxis can quickly be filled with infectious aerosols and become high-risk zones for disease transmission of Covid-19 and other respiratory diseases. The project aims to transform buses from one of the most risky environments into a safer one by redirecting the airflow in the vehicle from overpressure to negative pressure ventilation, similar to what is done in airborne disease isolation rooms in hospitals. Expected results and effects ** Denna text är maskinöversatt ** Covid-19 is spread mainly by close contact between persons through small and large droplets from the airways. This method being developed here eliminates aerosolized microorganisms and disinfects the ventilated air using the vehicle´s internal combustion engine, reducing the risk of infection with Covid-19 and other infectious diseases such as colds or flu for passengers and drivers alike. Planned approach and implementation The project is divided into three areas. 1) The construction of the first functional engine-driven ventilation prototype in a bus operated by Gamla Uppsala Buss, followed by a test and characterization phase in operation. 2) Investigation of infectivity and reduction of pathogens in the air. 3) Implementation and characterization of engine-based air sanitation in light vehicles, such as minibuses, taxis and/or ambulances. All activities are carried out within 12 months.
