Reducing pollutants can improve the quality of the air we breathe.

Air quality is a reference to how much pollution is in the air we breathe. Good air quality indicates cleaner, clearer and less polluted air, which is good for our health and the health of our environment. Poor air quality indicates pollution levels that may be harmful to the health of the population or the environment around us.

Understanding and reducing the sources of air pollutants can help us to improve the quality of the air we breathe.

Outdoor air quality

Outdoor air quality is affected by the types and amount of pollutants released into the air as well as weather conditions such as wind, precipitation, temperature and topography.

Wildfire smoke

See our wildfire smoke page for information and resources on staying healthy during wildfire smoke events.

Indoor air quality

The best way to improve indoor air quality is to reduce or eliminate sources of pollutants and provide adequate ventilation. See HealthLink BC's indoor air quality resource for more information.
