The U.S. outdoor air quality monitoring system market is projected to grow to USD 2.08 billion by 2034, expanding at a CAGR of 7.1%, according to Polaris Market Research. The report, “U.S. Outdoor Air Quality Monitoring System Market Size, Share, Trends, Industry Analysis Report By Type, Component, Category, Pollutants – Forecast 2025–2034” provides an in-depth view of market dynamics and future trends.
Air quality monitoring systems are designed to measure pollutants such as PM2.5, PM10, O₃, NO₂, CO, and SO₂ in real time. These solutions are widely used by governments, municipalities, industries, and environmental agencies to monitor air quality levels, detect pollution sources, and ensure compliance with regulations.
One of the major growth drivers is the rising occurrence of wildfires in California, Oregon, and Colorado, which release high levels of particulate matter and smoke. With wildfires intensifying due to climate change, the demand for real-time, mobile, and networked monitoring technologies is rising, allowing authorities to issue early warnings and safeguard public health.
The expansion of smart city initiatives is another critical factor. Cities are integrating IoT-enabled environmental sensors into urban infrastructure to provide hyper-local air quality insights accessible via apps and dashboards. This real-time data helps manage pollution from traffic and industrial areas while supporting urban planning. As federal and private investments in smart cities increase, demand for scalable, cost-efficient monitoring systems is expected to grow significantly.
Key Highlights:
- Fixed outdoor systems dominated with 71.35% market share as they are widely used by government agencies and industries for regulatory compliance, long-term data collection, and public health monitoring.
- Ozone monitoring generated USD 232.98 million in 2024, as ground-level ozone remains a critical air pollutant formed through reactions between NOx and VOCs in sunlight.
- Major players include 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.
Market Segmentation:
- By Type: Fixed Outdoor Systems, Portable Outdoor Systems
