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.

Air Quality Monitoring System Market Growth Drivers and Challenges:
Growth Drivers
-
Growing Public and Private Programs to Conserve the Environment – Through the implementation and regular monitoring of various government programs, such as the Clean Air Act, which has been the primary federal law governing air quality in the United States since 1970, North America has become significantly less polluted than before. Over 41 areas with high carbon dioxide levels were improved to meet air quality standards. Furthermore, these controls reduced respiratory disease prevalence and premature death rates in the U.S. According to the Environmental Protection Agency in the US, stated that the concentrations of air pollutants such as carbon monoxide improved by 73% from 1990 to 2020, followed by 86% for nitrogen dioxide per year, 25% for ozone, 26% for coarse particulates for 24 hours, 41% for fine particles, and 91% for sulfur dioxide.
- Rising levels of Household air pollution - There are around 2.4 billion people worldwide cooking on open fires or stoves fueled by kerosene, biomass, and coal, which causes harmful household air pollution and is a major cause of premature deaths. As reported by the World Health Organization (WHO), household air pollution resulted in 3.2 million deaths per year in 2020, including more than 2,37,000 deaths among children under 5 years of age around the globe.
- Increasing Air Particulate Associated Disorders – Particulate matter causes many health problems, including premature deaths, irregular heartbeats, aggravated asthma, impaired visibility, and respiratory signs such as coughing, irritation of the airways, and difficulty breathing. Based on the information provided by the EPA, fine particles (PM2.5) are the main cause of reduced visibility, also referred to as haze, in some parts of the United States.
- Rise in the Amount of Carbon Dioxide Emitted by Road Transportation - The burning of fossil fuels results in the emission of carbon dioxide into the atmosphere, which damages the environment. Approximately 25% of the EU's total CO2 emissions in 2019 were attributed to transport, with road transportation accounting for 71.7%.
- Growing Adoption of Smart Homes – Air Quality Monitoring System market provides humans to live in smart homes in better environmental conditions by monitoring pollutants. Furthermore, home automation sensors are installed in smart homes that can detect smoke at an earlier stage of fire, and it is anticipated to surge the growth of the market by the end of 2035. As per the estimations, the number of smart homes in the world is estimated to reach 4,500 million by 2050, from a baseline of 2,200 million in 2020
Challenges
- High Costs Associated with the Product - The device has a high installation and maintenance cost. In addition, these systems consume a high amount of power, have a large volume, and are heavy, which increases the overall cost of installation. As a result, emerging economies and rural areas are expected to see a lower adoption rate over the forecast period, thereby hindering the market growth.
- Slow Adoption Rate of Advanced Technology for Measuring Air Quality
- Poor Execution of Air Pollution Management Reforms in Developing Countries

Air Quality Monitoring System Market Segmentation:
Product Segment Analysis
The global air quality monitoring system market is segmented and analyzed for demand and supply by-products into indoor, outdoor, and wearable. Among these three segments, the outdoor segment is expected to gain the largest market share over the forecast period. The growth of the segment can be attributed to an increase in the number of outdoor air pollution sources, including emissions from vehicles, the burning of fuels, bushfire smoke, airborne dust, and vegetation-related emissions. Moreover, a variety of health problems, including cancer, heart disease, stroke, and respiratory problems, have been associated with outdoor air pollution. As per the reported data, nearly 4.2 million premature deaths worldwide were attributed to outdoor air pollution in 2019 in both urban and rural areas. The outdoor air monitoring system measures particulate matter in air pollutants, and dangerous gases such as Ozone, NO2, VOCs, and CO2, as well as assists in determining temperature, moisture, rain, wind speed, solar radiation, and noise levels. In addition, the portable air quality monitoring system market is being increasingly adopted by people for monitoring outdoor pollution, as they are easy to use, and this is further expected to drive the segment’s growth in the market.
Pollutants Segment Analysis
The global air quality monitoring system market is also segmented and analyzed for demand and supply by pollutants into chemical, particulate matter, and biological. Among these segments, the chemical segment is expected to garner a significant share in the coming years owing to the growing levels of chemical air pollutants globally. A majority of chemical pollutants are generated by transportation means such as road vehicles, trains, ships, and airplanes. They emit CO2, organic volatiles (VOCs), and heavy metals as pollutants. An air quality monitoring system measures such chemical pollutants, which can harm human health and the environment. Thus, this factor is expected to have a significant impact on segment growth in the future.
