Air Quality Monitoring System Market Report 2026

The air quality monitoring system market size has grown strongly in recent years. It will grow from $6.98 billion in 2025 to $7.66 billion in 2026 at a compound annual growth rate (CAGR) of 9.8%. The growth in the historic period can be attributed to increasing industrial emission monitoring needs, expansion of urban environmental monitoring programs, rising government focus on pollution control, wider deployment of fixed monitoring stations, improvements in sensor accuracy and reliability.

The air quality monitoring system market size is expected to see rapid growth in the next few years. It will grow to $11.25 billion in 2030 at a compound annual growth rate (CAGR) of 10.1%. The growth in the forecast period can be attributed to increasing investments in smart city infrastructure, rising adoption of iot-enabled environmental monitoring, expansion of real-time air quality data platforms, growing demand for predictive pollution analytics, increasing integration with regulatory reporting systems. Major trends in the forecast period include increasing deployment of networked air quality sensor systems, rising use of real-time pollution monitoring platforms, growing adoption of cloud-based air quality analytics, expansion of mobile and remote sensing monitoring solutions, enhanced focus on regulatory compliance and data accuracy.

The rise in air pollution levels is expected to drive growth in the air quality monitoring system market in the coming years. Air pollution involves the release of pollutants into the atmosphere, including carbon dioxide, methane, and other chemically active gases. Increasing pollution levels fuel demand for air quality monitoring systems, which measure and track these pollutants. For example, in November 2024, the Global Carbon Budget, a Japan-based annual scientific assessment, reported that fossil carbon dioxide emissions rose to 37.4 billion tonnes, a 0.8% increase from the previous year. Therefore, growing air pollution is supporting expansion in the air quality monitoring system market.

The increasing adoption of smart homes is also expected to bolster the air quality monitoring system market. A smart home is a residential setup where appliances and devices can be remotely controlled via the internet using mobile or networked devices. Smart homes integrate various sensors and devices, including air quality monitoring systems, to provide real-time data on indoor air conditions. For instance, in 2023, Oberlo reported that over 60.4 million households in the US actively used smart home devices, a 3% increase from 57.4 million households in 2022. In 2023, this represents 46.5% of all US households. Therefore, the growing prevalence of smart homes is driving demand for air quality monitoring systems.

Companies in the air quality monitoring system market are focusing on advanced multi-sensor technologies to enhance detection accuracy, ensure compliance with global standards, and meet rising demand for intelligent monitoring solutions. Multi-sensor modules integrate multiple air quality parameters - such as particulate matter, volatile organic compounds (VOCs), and other harmful gases - into a compact unit for precise environmental measurement. For example, in August 2024, Renesas Electronics Corporation, a Japan-based semiconductor solutions provider, launched the RRH62000, a multi-sensor air quality module designed to deliver accurate, real-time monitoring across various applications. Powered by a Renesas microcontroller (MCU), the module intelligently manages sensor operations and can be used in air purifiers, smoke detectors, HVAC systems, weather stations, and smart home devices. Its robust firmware ensures compliance with global air quality standards, enabling manufacturers to provide more reliable and efficient monitoring solutions.
