- Air Quality
Air Quality Basics
Clean, healthy air is essential to our day-to-day well-being, our long-term health, and the health of our environment. The Clean Air Agency focuses its efforts on reducing air pollutants that pose the greatest health risks to our region – which include criteria air pollutants, air toxins and greenhouse gases.
Air Pollution & Your Health
Our long-term vision is for all people to benefit from clean healthy air all the time, everywhere. To achieve this, we target the largest sources of the most harmful pollutants in our region to protect public health.
Wood Smoke & COVID-19
If you have or are recovering from COVID-19, you may be at an increased risk of health effects from exposure to wood smoke due to COVID-19’s impact on heart and or lung function.
About the Air Quality Index
The Air Quality Index (AQI) is a color-coded tool for reporting daily air quality. It provides simple information on local air quality, the health concerns for different levels of air pollution, and how you can protect your health when pollutants reach unhealthy levels.
The Agency monitors air pollution across our four counties.
Criteria Air Pollutants
Our job is to ensure the people of King, Kitsap, Pierce and Snohomish counties have clean, healthy air to breathe. We do this in part by ensuring our region meets federal air quality standards for six common air pollutants known as "criteria air pollutants."
Air toxics are a group of over 400 pollutants known or suspected to cause a number of health problems, including cancer and birth defects, and damage to lungs and immune and nervous systems.
Gases that absorb and trap heat in the atmosphere are called “greenhouse gases.” As the amount of greenhouse gases in our atmosphere increases, the amount of heat trapped by the atmosphere also increases, causing the overall warming of the planet.
