ISF Impact Series Webinar – Indoor Air Pollution During and After Regional Smoke Events

Wildfire smoke is becoming a growing threat to public health across the United States, affecting millions of people far beyond fire-prone regions. This talk explores how smoke infiltrates homes and buildings, how well different air cleaning strategies protect occupants, and why wildfire smoke can linger indoors long after outdoor air clears. Drawing on data from hundreds of indoor air monitors and recent studies of air filtration and surface contamination, the presentation highlights practical, science-based strategies to reduce exposure and protect indoor environments during and after smoke events.
