Some areas in the Northwest have “unhealthy” air quality

The primary cause is smoke from wildfires

Smoke from wildfires continues to plague areas of Washington, Oregon, California, Idaho, Nevada, and Wyoming. According to AirNow.gov, the five cities in the United States with the worst air quality Tuesday were:

  • Cheeka Peak, Seattle-Bellevue-Kent Valley, and Bellingham in Washington;
  • Yreka, California; and
  • Shady Cove, Oregon.

The information below from the National Weather Service reinforces the advice that the least expensive dust masks available at the local hardware store (or a bandana tied over your face) provide almost no protection from smoke. The microscopic particles in smoke from vegetation fires are so small that they cruise right through a mask that may work fine for filtering out dust from working with wood, for example.  As they said, choose a mask called a “particulate respirator” that has the word “NIOSH” and either “N95” or “P100” printed on it.
