Air Quality Monitoring System Market Outlook:
Air Quality Monitoring System Market size was valued at USD 5.62 billion in 2025 and is likely to cross USD 11.58 billion by 2035, registering more than 7.5% CAGR during the forecast period i.e., between 2026-2035. In the year 2026, the industry size of air quality monitoring system is assessed at USD 6 billion.
The growth of the market can be attributed to the increasing number of pollutants in the air along with rising pollution levels. Air pollution is emerging as a significant global concern. According to the WHO data, almost 99% of the global population breathes air with pollution levels exceeding WHO guidance limits, mainly in low- and middle-income countries, which have the highest levels of pollution. To protect the environment, air quality monitoring systems are of the utmost importance. Environmental sensors are used in these systems to gather, display, and record information about air pollutants, temperatures, and humidity levels. In addition to monitoring air quality, these systems also assist in preventing and controlling air pollution.
Additionally, there are several factors anticipated to contribute to the growth of the global air quality monitoring system market, including higher levels of pollution generated by industrial operations and the extent of pollution exposure among industry workers. As part of their everyday operations, many industrial plants emit pollutants such as fine dust, acid gases, lead, mercury, sulfur dioxide, and carcinogens. Consequently, it harms the environment and the worker's health. Air quality monitors are heavily used in such industries to examine emissions, dust deposition, and chemical reactions and to measure deviations from air quality standards. Furthermore, governments across developing economies are taking steps to make industrial operations more environmentally friendly, which is expected to propel the demand for air quality monitoring systems over the forecast period.
