Oregon's Air Is Usually Clear — Until Wildfire Season
According to the American Lung Association's 2026 report, Portland's year-round particle pollution ranks among the cleanest in the nation. But during summer and fall wildfire season, smoke can send particle levels soaring for short stretches.
2nd worst in the nation, averaging 33.5 unhealthy days per year
Ranked 16th nationally, averaging 9 unhealthy days per year
Among the cleanest year-round nationally; short-term particle pollution graded C
- Rankings are based on the American Lung Association's 2026 report, analyzing 2022–2024 monitoring data. The association cites wildfires as a major source of particle pollution.
- In August 2026, the Oregon Department of Environmental Quality (DEQ) issued air quality advisories for 27 of the state's 36 counties due to wildfire smoke.
- Around the same time, Portland briefly ranked as the major city with the worst air quality in the world on IQAir's air monitoring rankings.
- When smoke is present, the standard guidance is to stay indoors and keep windows closed.
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.
Portland Tap Water: Among the Softest in the U.S.
Portland's tap water comes mainly from rain and snowmelt in the Bull Run watershed inside the Mount Hood National Forest. According to the Portland Water Bureau's 2026 report, it is very soft water with minimal minerals, and a filtration facility is currently under construction.
U.S. Geological Survey (USGS) scale: 0–60 soft, 61–120 moderate, 121–180 hard, 181+ very hard. Portland figures are from the 2026 report (2025 data).
Portland Tap Water
0.5 gpg
Bull Run source hardness · 7–11 mg/L · soft water
- Serves about 1 million people; supplemented with Columbia South Shore groundwater in summer and fall
- Disinfected with chlorine and ammonia (chloramine), with corrosion control treatment
- Lead 90th percentile: 4.9 ppb — 0 of 98 homes exceeded the action level
- No known lead service lines; PFAS not detected
Filtration Facility Under Construction

Scheduled to Begin Operation
- A $2.56 billion filtration facility is currently under construction
- In 2025 raw-water testing, Cryptosporidium was detected in 54 of 193 samples
- Detections occurred mainly during the rainy season, and the Water Bureau publishes the results
A Water Purifier Before a Softener
Bull Run water measures around 0.5 gpg in hardness, so scale buildup is rarely a concern. For most households, a drinking-water purifier comes first.
Water Can Change in Summer and Fall
The Water Bureau blends in groundwater during summer and fall. Groundwater hardness is about 80 mg/L — higher than Bull Run water — so you may notice a difference in taste during these months.
Chloramine Taste and Odor
Portland disinfects with a combination of chlorine and ammonia. It stays within safety standards, but some households are sensitive to the taste and odor.
These figures are system-wide data published by the agencies; actual water quality at your home may vary by water provider, season, and building plumbing. For Beaverton, Tigard, and other areas, check your local water provider's annual quality report.

Do you install in Beaverton or Tigard too?
Yes — installation is available throughout the greater Portland area, including Beaverton and Tigard. For the Willamette Valley, including Eugene and Corvallis, send us your address and we'll confirm availability.
Do air purifiers help during wildfire season?
Air purifiers help reduce indoor fine dust from wildfire smoke. On heavy smoke days, keep windows closed, stay indoors, and run your air purifier.
Is Portland tap water safe to drink as is?
According to the Portland Water Bureau's 2026 report, no households exceeded lead standards and no PFAS was detected. A filtration facility is under construction with a 2029 target start date, so some households use a water purifier in the meantime.
Do I need a water softener in Oregon too?
Portland's Bull Run water is soft at about 0.5 gpg, so most households don't need a softener. Homes on private wells should decide based on a water test.
How are filters maintained after installation?
During your rental, a Coway specialist visits every 6 months to replace filters and inspect your products. Maintenance is included in your rental fee.
