Indoor air filtration during wildfires:
Impacts on air quality and health

Wildfire smoke can infiltrate the indoor environment and expose occupants to harmful air pollutants. This rapid review examines how effective indoor air filtration and cleaning is at reducing concentrations of wildfire-related pollutants, and if air cleaners can be protective of health.

My ongoing love affair with portable air cleaners

Systematic reviews provide a framework for rigorously assessing scientific evidence. Our new systematic review on portable air cleaners (PACs) for wildfire smoke uses a standardized tool for evaluating the effectiveness of interventions. This personal commentary explains why the results from this tool may seem inconsistent with public health recommendations to use PACs.

Wildfire smoke air pollution: New approaches needed to protect people affected

Exposure to wildfire smoke has increased across North America over the past 20 years, offsetting air quality improvements achieved through decades of emissions regulations. This trend is likely to persist under climate change, challenging us to explore new approaches to safeguard populations from smoke pollution.

Invitation to participate in Canadian Centre for Climate Services Survey

ClimateData.ca will soon release future return periods projections, including:

  • 1 in 5- and 1 in 20-year maximum and minimum temperature
  • 1 in 5-, 1 in 20-, and 1 in 50-year maximum daily precipitation 

Return periods are a metric for quantifying the frequency and intensity of extreme weather events. This data informs climate change adaptation planning by quantifying rare but potentially high-impact extreme events. 

The Canadian Centre for Climate Services (CCCS) invites you to complete a short survey (~15 minutes) to help ensure this dataset meets your needs. Your feedback will directly influence how the CCCS presents and prioritizes data development on Climatedata.ca.

SURVEY: Return Period Indices

Deadline to complete the survey is July 7. For question about the survey, please contact Nouran Nour (Nouran.Nour@ec.gc.ca).
