Climate Adaptation – Indoor Air Quality and Health

EPA has developed guidance for improving or maintaining indoor air quality within homes, schools, and businesses.

Indoor air quality refers to the air in and around buildings and structures, especially as it relates to the health and comfort of building occupants.

Indoor fungi and mold

Changes in precipitation patterns and an increase in extreme weather events may complicate and/or worsen indoor air quality. Events that lead to a damp indoor environment can create ideal conditions for the growth of indoor fungi and mold.

Wildfire smoke and indoor air quality

Changing environmental conditions are increasing the severity of wildfires and lengthening fire season. Wildfire smoke can infiltrate buildings, which degrades indoor air quality. 

Wildfire smoke contains particulate matter and other toxic particles that are hazardous to breathe. Children, the elderly, those who work outdoors, are pregnant, and/or who experience respiratory issues are particularly vulnerable. However, extended exposure to high levels of wildfire smoke is hazardous to healthy groups as well.
