There are many factors that can lead to poor air quality, but the two most common are related to elevated concentrations of ground-level ozone or particulate matter.
What is causing smoke in Spokane?
Like much of the western U.S., the Spokane area is experiencing more frequent periods of unhealthy air quality due to wildfires. Wildfire smoke contains very small particles and gases, including carbon monoxide. These particles can get into your eyes and lungs where they can cause health problems.

Can bad air quality make you sick?
Long-term exposure to particulate pollution can result in significant health problems including: Increased respiratory symptoms, such as irritation of the airways, coughing or difficulty breathing. Decreased lung function. Aggravated asthma.
Does rain improve air quality?
Studies have shown that rainfall can improve air quality. The larger the initial concentration of particulate matter, the better the rainfall cleaning effect is, and the clearer effect of PM10 is better than that of PM2.5 (Zhou et al., 2020).
Where is the smoke coming from?
Smoke occurs when there is incomplete combustion (not enough oxygen to burn the fuel completely). In complete combustion, everything is burned, producing just water and carbon dioxide. When incomplete combustion occurs, not everything is burned. Smoke is a collection of these tiny unburned particles.
