While the Agency’s mandate and mission are to focus on emissions that go into the air we all breathe and ambient (outdoor) air quality, we spend a lot of our time in indoor environments. Air pollution from outside can impact indoor air quality, as well as activities within the building. Because we spend so much of our time indoors, it’s important to be aware of and address indoor air quality.  

Our Department of Health, local health departments, and the Lung Association offer some great resources to help improve the indoor air quality in homes and buildings. Some of these are listed below: 

• Public Health – Seattle & King County
• Tacoma-Pierce County Health Department
• Snohomish County Health Department
• State Health Department
• Washington American Lung Association

When outdoor air pollution levels are very high, such as during a wildfire smoke event, it’s especially important to address indoor air quality through use of an air cleaner or purifier that can reduce fine particle pollution. One affordable way to reduce fine particle pollution in these events is to construct a DIY Air Filter.
