According to Fortune Business Insights the global air quality monitoring system market size was valued at USD 4.54 billion in 2025 and is projected to be worth USD 4.82 billion in 2026 and reach USD 9.25 billion by 2034, exhibiting a CAGR of 8.49% during the forecast period. Growth is driven by increasing concerns regarding air pollution, health risks, and stringent environmental regulations. Air Quality Monitoring Systems (AQMS) are devices and software solutions used to measure, analyze, and monitor air pollution levels. These systems detect pollutants such as PM2.5, PM10, carbon monoxide (CO), nitrogen dioxide (NO₂), sulfur dioxide (SO₂), and ozone (O₃). They are widely used in industrial facilities, urban environments, residential buildings, and government monitoring stations to ensure environmental safety and regulatory compliance.
