Seattle Air: Wildfire-Season Particle Pollution Ranks Near the Top Nationally
In the American Lung Association's 2026 report, the Seattle–Tacoma area ranked eighth worst in the nation for short-term particle pollution. The association cites wildfires as a major source of particle pollution.
#8 nationally, averaging 11.3 unhealthy days per year (Snohomish County)
Averaging 4.3 unhealthy days per year (King County)
Averaging 5 unhealthy days per year; ozone among the cleanest nationally
When wildfire smoke is present, the City of Seattle recommends a HEPA filter air purifierto reduce indoor air pollution.
- On August 3, 2026, the Washington State Department of Ecology issued a wildfire smoke alert for the Puget Sound region, including King, Pierce, Snohomish, Kitsap, and Thurston counties.
- The department advised staying indoors, running portable air purifiers, and setting heating and cooling to recirculate indoor air.
- The City of Seattle cautions against using air purifiers that produce ozone.
- Rankings are based on the American Lung Association's 2026 report, analyzing 2022–2024 monitoring data.
What an Air Purifier Can Do
- Reduce indoor fine dust from wildfire smoke
- Manage indoor air during wildfire season with windows closed
- The U.S. Environmental Protection Agency (EPA) notes that air purifiers cannot remove every pollutant. On heavy smoke days, limiting outdoor activity comes first.
Tacoma Tap Water: No PFAS Detected in the Green River Source
According to Tacoma Water's 2025 report, no PFAS was detected in the Green River, the primary source, and two PFAS compounds in supplemental groundwater tested below state standards. Tap water meets state and federal standards.
Green River water is filtered, ozonated, and chlorinated before delivery. If taste or chlorine odor bothers you, a purifier helps. Check your local utility's annual water quality report for details.
