U.S. Outdoor Air Quality Monitoring System Market Size, Share, Trends, Industry Analysis Report, By Type (Fixed Outdoor Systems, Portable Outdoor Systems), By Component, By Category, By Pollutants – Market Forecast, 2025–2034
Description
The U.S. outdoor air quality monitoring system market size is expected to reach USD 2.08 Billion by 2034, according to a new study by Polaris Market Research. The report “U.S. Outdoor Air Quality Monitoring System Market Size, Share, Trends, Industry Analysis Report By Type (Fixed Outdoor Systems, Portable Outdoor Systems), By Component, By Category, By Pollutants – Market Forecast, 2025–2034” gives a detailed insight into current market dynamics and provides analysis on future market growth.
An outdoor air quality monitoring system is used to measure and analyze the presence of pollutants in the outdoor environment. It monitors substances such as particulate matter (PM2.5, PM10), ozone (O₃), nitrogen dioxide (NO₂), carbon monoxide (CO), and sulfur dioxide (SO₂) in real time. These systems help governments, industries, and environmental agencies assess air quality levels, track pollution sources, and ensure compliance with environmental regulations.
The rising frequency and intensity of wildfires across states such as California, Oregon, and Colorado have made air quality monitoring more critical than ever. Wildfires release massive amounts of smoke and fine particulate matter (PM2.5), which can travel hundreds of miles, affecting the air quality of entire regions. These events are directly linked to climate change, which is causing drier conditions and longer fire seasons. In response, state and local governments are ramping up investments in real-time outdoor air monitoring systems to provide early warnings and public health advisories during wildfire events. Residents rely on this data to make decisions about outdoor activities and protective measures. The growing need to respond quickly to environmental emergencies is driving demand for more robust, mobile, and networked air quality monitoring technologies. This trend is expected to continue in the coming years as climate risks increase, making outdoor air quality systems essential for disaster preparedness and response.
The expansion of smart city initiatives across the U.S. is creating strong momentum for outdoor air quality monitoring systems. Cities are increasingly integrating environmental sensors with smart infrastructure to collect and analyze real-time data on air pollution, temperature, noise, and traffic. Internet of Things (IoT)-based air quality monitors allow city managers and residents to access hyper-local data through mobile apps or dashboards. This enables quicker responses to pollution spikes and better urban planning based on air quality trends. As smart city programs continue to receive federal funding and private investment, the role of environmental monitoring becomes more central. For example, placing monitors near traffic intersections or industrial areas helps manage emissions more effectively. The push toward data-driven governance is encouraging municipalities to install scalable and affordable monitoring systems that are easy to maintain and integrate with broader smart infrastructure, further fueling the U.S. outdoor air quality monitoring system market demand.
U.S. Outdoor Air Quality Monitoring System Market Report Highlights
The fixed outdoor systems segment accounted for 71.35% share during the forecast period as fixed stations are often used by government agencies, municipalities, and large industrial facilities to comply with environmental regulations, generate long-term air quality data, and support urban planning or public health initiatives.
The ozone segment accounted for USD 232.98 million revenue in 2024 as ozone at ground level is a harmful air pollutant formed by chemical reactions between nitrogen oxides (NOx) and volatile organic compounds (VOCs) in the presence of sunlight.
A few key market players are Aeroqual; Airgradient; ENVEA GLOBAL; Horiba, Ltd.; Kunak Technologies; Met One Instruments, Inc.; Oizom Instruments Pvt. Ltd.; PerkinElmer, Inc.; Prana Air; Siemens AG; and Teledyne Technologies Incorporated.
