Clean Air Solutions / April 30, 2019 / -- According to the American Lung Association’s ‘State of the Air’ report for 2018, air quality across much of the United States has been on a positive upward trend thanks in large part to the success of the Clean Air Act. The State of the Air report identifies the following cities for being most likely to have the best outdoor and indoor air quality due to low year-round particle pollution:
- Cheyenne, WY
- Urban Honolulu, HI
- Casper, WY
- Bismarck, ND
- Kahului-Wailuku-Lahaina, HI
- Pueblo-Canon City, CO
- Elmira-Corning, NY
- Palm Bay-Melbourne-Titusville, FL
- Sierra Vista-Douglas, AZ
- Wenatchee, WA
The ALA, however, notes that there are different types of air pollution. For example, while Fairbanks, Alaska is one of the cleanest cities in terms of ozone pollution levels, it is actually the worst when it comes to particle pollution. This disparity is due to the number of homes in the city that rely on burning wood for cooking and heating.
As for why these cities have clean air? It’s actually a combination of factors. Basically, even if the air outside is clean in your city, many indoor home environments can still have high concentrations of airborne contaminants, hence the need for air purification.
On the other hand, the cities where homes and commercial buildings seriously need high efficiency filtration systems are mostly concentrated in California, where wildfires and high traffic volume have combined to create poor ambient air quality. Los Angeles, Bakersfield, Visalia, Fresno, Sacramento, San Diego, Modesto, and Redding take the top spots on the dirtiest air list, even as California officials race to pass measures to make air safe and clean to breathe.
So why then do America’s cleanest cities still need high efficiency air filters?
