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

Climate change is expected to complicate and/or worsen indoor air quality by creating conditions that may be ideal for the growth of indoor fungi and mold.

Wildfire smoke and indoor air quality

Climate change is increasing the severity of wildfires and lengthening fire season. Wildfire smoke can infiltrate buildings, degrading indoor air quality. Wildfire smoke contains particulate matter and other toxic particles that are hazardous to breathe. Outdoor workers, children, the elderly, pregnant people, and those with respiratory issues are particularly vulnerable. However, extended exposure to high levels of wildfire smoke is hazardous to healthy groups as well.
