Air Pollution
Air pollution is invisible. It travels freely
in the air and enters our buildings
through open doors and windows, and
through ventilation systems
Virus Transmission
Risk
Why are virus transmission risks greater
in indoor spaces, and what can be
done to reduce these risks?
Poor Ventilation
Carbon dioxide (CO2) levels increase
in poorly ventilated spaces which
impacts cognitive function and
increases exposure to air pollution and
virus transmission risks
