Spokane, Washington, boasts stunning natural beauty, but its air quality can fluctuate, impacting residents' health and outdoor activities. Understanding the Air Quality Index (AQI) is crucial for making informed decisions about your daily life. This comprehensive guide will help you navigate Spokane's air quality, understand the AQI, and learn how to protect yourself and your family.
Understanding the Air Quality Index (AQI)
The AQI measures how clean or polluted the air is. It focuses on five major pollutants: ground-level ozone, particle pollution (PM2.5 and PM10), carbon monoxide, sulfur dioxide, and nitrogen dioxide. Each pollutant has a separate AQI value; the overall AQI is the highest of these values.
The AQI scale ranges from 0 to 500, with higher numbers indicating greater pollution and potential health risks. Here's a breakdown:
- 0-50 (Good): Air quality is considered satisfactory, and air pollution poses little or no risk.
- 51-100 (Moderate): Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
- 101-150 (Unhealthy for Sensitive Groups): Members of sensitive groups may experience health effects. This includes children, older adults, and people with respiratory diseases.
- 151-200 (Unhealthy): Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.
- 201-300 (Very Unhealthy): Health warnings of emergency conditions. Everyone may experience more serious health effects.
- 301-500 (Hazardous): Health alert: everyone may experience serious health effects.

Factors Affecting Spokane's Air Quality
Spokane's air quality is influenced by several factors:
- Wildfires: Smoke from wildfires, both nearby and distant, significantly impacts air quality, often leading to unhealthy AQI levels, especially during summer and fall. This is a major contributor to poor air days.
- Inversions: Temperature inversions trap pollutants close to the ground, worsening air quality. These are more common in winter months.
- Industrial emissions: Industrial activities within and around Spokane contribute to air pollution.
- Vehicle emissions: Traffic congestion contributes to elevated levels of pollutants like nitrogen dioxide.
- Construction: Dust and particulate matter from construction projects can temporarily affect air quality in localized areas.
Protecting Yourself from Poor Air Quality
When the AQI is high, take steps to protect your health:
- Limit outdoor activities: Avoid strenuous outdoor activities when the AQI is unhealthy or very unhealthy.
- Stay indoors: Spend more time indoors, especially in air-conditioned spaces.
- Use air purifiers: Consider using air purifiers with HEPA filters to remove pollutants from your indoor air. These are particularly helpful during wildfire smoke events.
- Monitor your health: Pay attention to any respiratory symptoms and seek medical attention if needed. Asthma sufferers should be especially vigilant.
- Keep your windows closed: Reduce infiltration of polluted air from outside.
