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.

Seattle & Eastside
Seattle and the areas east of Lake Washington
- Seattle
- Bellevue
- Newcastle
This is our highest-volume area for consultations and installs. The American Lung Association's 2026 report ranked this area #8 nationally for short-term particle pollution, and air purifier inquiries rise sharply during wildfire season.
Can an air purifier be set up in a Seattle apartment?
Yes. We recommend both a living-room model and a bedroom model based on room size, and if the building has delivery restrictions, let us know the building name and we'll confirm in advance.
Snohomish County
Korean communities north of Seattle
- Lynnwood
- Edmonds
- Everett
The American Lung Association's 2026 report recorded the highest short-term particle pollution levels in this county. It was also included in the Washington State Department of Ecology's wildfire smoke advisory in August 2026.
Is wildfire smoke especially bad in Lynnwood and Edmonds?
The American Lung Association's report ranked Snohomish County #8 nationally for short-term particle pollution. During wildfire season, we recommend a HEPA air purifier along with managing indoor ventilation.
South King · Pierce Counties
Areas south of Seattle including Federal Way and Tacoma
- Federal Way
- Tacoma
- University Place
- Graham
- Gig Harbor
Served by Tacoma Water, where no PFAS was detected in the Green River source. This area was also under the August 2026 wildfire smoke advisory, so many households consult on an air purifier and water purifier together.
Can I drink Tacoma tap water without a purifier?
Per Tacoma Water's 2025 report, tap water meets state and federal standards. If chlorine odor or taste is a concern for your household, we can go over a purifier option together.
Kitsap · Olympic Peninsula
West of Puget Sound
- Bremerton
- Allyn
- Matlock
- Aberdeen
Kitsap County was included in the August 2026 wildfire smoke advisory. In outlying areas like Aberdeen, some homes rely on a private well, so we review your water test results together.
Do you install for homes on private wells?
Yes. Well water quality varies from home to home, so sharing your test results or a description of your water's taste and condition helps us recommend the right purifier.
Southwest
Southwest area bordering Portland
- Vancouver
- Centralia
- Rainier
An outlying area farther from the branch, where water suppliers vary by town, so we share the relevant water quality report with you before the visit.
Does the 6-month maintenance plan cover farther areas like Vancouver?
Yes, as long as your area is serviceable you'll get the same 6-month visit schedule, coordinated together with nearby areas.
East
Tri-Cities Area
- Kennewick
Eastern Washington, including Spokane, rated among the cleanest in the nation for ozone in the American Lung Association's report, though the drier climate still brings seasonal shifts in particle pollution, which we go over during consultation.
Does the 70-mile radius rule apply to Kennewick too?
It depends on the exact distance from our branch. Share your address and we'll confirm whether installation is available.
Installation may be difficult in areas more than 70 miles from a Coway branch or authorized dealer.

Does an air purifier help with Seattle wildfire smoke?
The City of Seattle advises using a HEPA-filter air purifier to reduce indoor air pollution during wildfire smoke. Keep windows closed and set heating and cooling to recirculate while running it.
Do I need an air purifier in every room?
On heavy smoke days, it's most effective to turn the room your family spends the most time in into a clean-air space. We'll match the unit to your room size — like the Square Fit 25-pyeong for living rooms or the 409 ft² model for bedrooms.
Is Washington tap water safe to drink?
According to Tacoma Water's 2025 report, tap water meets state and federal standards, and no PFAS was detected in the Green River source. Households usually choose a purifier for taste and chlorine odor concerns.
