Air Quality Sensor Market Report 2026

The air quality sensor market size has grown rapidly in recent years. It will grow from $6.31 billion in 2025 to $7.04 billion in 2026 at a compound annual growth rate (CAGR) of 11.5%. The growth in the historic period can be attributed to rising awareness of air pollution impact, increasing government focus on environmental monitoring, early deployment of industrial safety monitoring systems, growth in urban pollution concerns, rising health safety consciousness.

The air quality sensor market size is expected to see rapid growth in the next few years. It will grow to $10.74 billion in 2030 at a compound annual growth rate (CAGR) of 11.1%. The growth in the forecast period can be attributed to rising focus on smart environmental monitoring, increasing demand for indoor air quality safety, growing integration with smart home ecosystems, expansion of intelligent pollution tracking networks, rising emphasis on health oriented environmental systems. Major trends in the forecast period include increasing integration of smart air quality monitoring solutions, rising deployment of indoor and outdoor pollution detection devices, growing use of connected air monitoring platforms, expansion of real time air health tracking technologies, rising focus on preventive environmental health management.

The growing environmental pollution is expected to drive the growth of the air quality sensor market in the coming years. Environmental pollution refers to the contamination of air, water, or soil by harmful substances or pollutants, which negatively impact ecosystems, human health, and the climate. Environmental pollution is increasing due to rising industrial activities, urbanization, and the widespread use of fossil fuels, which release higher levels of pollutants into the environment. Air quality sensors are essential for monitoring environmental pollution as they provide real-time data on pollutant levels, enabling timely interventions and informed decision-making to reduce adverse health and environmental effects. For instance, in August 2024, according to a report published by the United States Environmental Protection Agency (EPA), a US-based government organization, approximately 66 million tons of pollutants were released into the atmosphere in the U.S. in 2023. Therefore, the growing environmental pollution is driving the growth of the air quality sensor market.

Major companies operating in the air quality sensor market are developing innovative products, such as compact air quality sensors, to provide real-time, accurate air quality data without requiring significant space or infrastructure. A compact air quality sensor is a small, portable device designed to monitor pollutants like particulate matter and gases in real-time. For instance, in March 2024, Vaisala Oyj, a Finland-based producer of environmental and industrial measurement solutions, launched the Air Quality Transmitter 560 (AQT560). The AQT560 is a gold-standard compact air quality sensor known for its wide detection range, covering PM1, PM2.5, and PM10, and its advanced calibration system and algorithms that ensure exceptional accuracy and efficiency. This sensor effectively measures aerosol particle concentrations from 0.3 to 10 microns, providing reliable detection of PM1 from combustion sources such as traffic, residential wood burning, and wildfires; PM2.5 influenced by long-range transport; and PM10 arising from abrasive activities like road dust, sandstorms, construction, and mining.

In February 2023, Molekule Group, a US-based consumer electronics company, acquired Aura Smart Air Ltd. for an undisclosed amount. With this acquisition, Molekule aims to expand its smart air purification portfolio and strengthen its presence in the connected home air quality market by integrating Aura Smart Air’s innovative technologies and customer base. Aura Smart Air Ltd. is a US-based technology company specializing in smart air purifiers and IoT-enabled air quality solutions.
