What is an air quality “Action Day”?

In winter, indoor burning restrictions, voluntary driving reductions, and public health recommendations are advised.

What can I do to protect myself from poor air quality?

Reducing exposure to poor air is as simple as being knowledgeable about how it can affect you and your family, such as knowing when to exercise or play outside. Even when indoors, some pollutants may pose health risks. Watch for air quality index advisories from the EPA and check out the up-to-date widget on the air quality website homepage to stay informed.
