COVID-19: Guidance on indoor ventilation during the pandemic

The Public Health Agency of Canada (PHAC) has developed this guide to inform Canadians about how indoor ventilation, in combination with other recommended public health measures, can reduce the spread of COVID-19. This guide also provides practical tips on how to improve indoor air, ventilation and filtration to help reduce the spread of COVID-19. While this guidance is intended to be used generally across indoor environments, its application will depend on:

  • occupancy
  • the type of building
  • the type of activity undertaken in the indoor setting
  • Canadian public health guidance related to COVID-19 has evolved as our understanding of COVID-19 improves. We continually review the evidence as it's produced and work with our partners across the country and around the world. This ensures that we integrate the most up to date and highest quality information into our guidance.
