The growth of the air pollution sensors market is primarily driven by rising air pollution globally caused by the use of household combustion devices, industrial facilities, motor vehicles, forest fires, and many other factors. The demand for air pollution sensors increases as air pollution levels rise, driving the need for environmental monitoring, tracking air pollution levels, and detecting trends related to it. Households are highly responsible for the rising air pollution. As revealed by the World Health Organization, 2.1 billion households relied on polluting fuels and technologies for cooking, and 99% of the global population lived in air pollution-prone places exceeding the WHO limits in 2023.

The air pollution sensors market is transitioning from specialized research instruments to mainstream elements of contemporary air-quality management. This is driven by increased policy pressure to achieve tighter air-quality goals, increased public and agency investment in distributed monitoring, and accelerating advances in low-cost sensor technologies and QA procedures as public health recommendations have become more stringent. For instance, the World Health Organization's Air Quality Guidelines of 2021 reduced recommended exposure levels for PM2.5, NOâ‚‚, and other pollutants and refocused world attention on air pollution's health cost; government authorities are responding with new standards and tighter monitoring requirements. These policy changes drive the need for more dense monitoring networks to detect hotspots, assess interventions, and show compliance.

Growth Drivers

  • Growing health awareness: People globally are increasingly aware of different health consequences of exposure to polluted air, including cardiovascular diseases, respiratory diseases, cancer, obesity, diabetes mellitus, allergies, and others. As a result, the demand for indoor air quality monitoring is increasing, likely to lead to a surge in the use of air pollution sensors. Key players in the market are also active in the development of indoor air pollution sensors. For instance, IKEA unveiled a new VINDSTYRKA air quality sensor in February 2023. The technology features a display to show PM2.5 levels, temperature, humidity, and TVOC.
  • Stringent environmental regulations and guidelines: Stringent environmental regulations are obligating the measurement and monitoring of air pollution levels for the protection of public health and the environment.  This is significantly fuelling the demand for air pollution sensors. In December 2024, the European Commission disclosed that a revised Ambient Air Quality Directive was enacted, which is obligating to lower the levels of 12 air pollutions, including nitrogen dioxide (NO2), particulate matter (PM2.5 and PM10), sulphur dioxide (SO2), nitrogen oxides (NOx), ozone (O3), benzene, carbon monoxide, arsenic, nickel, cadmium, and others. This is likely to lead to a growing adoption of air pollution sensors by environmental agencies to contribute to reducing air pollution by 2030. In addition, the U.S. Environmental Protection Agency issued guidance in January 2025 to make air pollution sensors accessible, perform period checks, use multiple sources to power the sensors, integrate cloud interfaces with sensors, place sensors away from pollutant sources, and many more.
  • The initiation of the smart cities: The demand and adoption of the air pollution sensors are anticipated to surge with rapid smart city initiatives and infrastructural development. As revealed by the International Telecommunication Union in September 2024, virtual sensors have become important in monitoring air pollutants in the execution of smart city initiatives.  Similarly, according to the disclosure by the Institute of Electrical and Electronics Engineers in July 2025, the IoT-based MQ135 sensors are delivering 95% accuracy in sensing air pollutants, including COâ‚‚, ammonia, and VOCs, allowing for high-resolution mapping in smart cities.

Challenges

  • High cost and maintenance: One of the key challenges of the market is low deployment of air pollution sensors owing to their high price, especially high-accuracy research-level sensors. The total expenses include initial purchases and costs for maintenance and calibration, which are critical to provide accurate and reliable data. This is likely to limit the adoption of advanced air pollution sensors in small and medium enterprises. In addition, the sophistication of the systems requires trained technicians, which can further add to the overall expenses.
  • Poor public awareness and lack of standardization:  Even though air pollution is a widely documented global phenomenon, several rural and developing areas lack knowledge of its adverse health effects and the tangible benefits of air quality information in real time. Moreover, data gathered by current sensors is not necessarily available or comprehensible to the general public. Along with this, inconsistent test standards, quality assurance practices, and data formats can limit the buyers and agencies from comparing the devices and accepting sensor network data.
