This press release delves into the market landscape, segmentation, regional dynamics, innovation trends, and key companies shaping the ecosystem through 2025 and beyond. The global air quality monitoring system market size is expected to reach USD 10.9 Billion by 2034, according to a new study by Polaris Market Research.

Market Overview

Air quality monitoring systems are devices and integrated networks that measure concentrations of pollutants like PM2.5, PM10, NO₂, CO, O₃, SO₂, VOCs, as well as environmental variables such as temperature and humidity. These systems are being employed for real‑time pollutant sensing in outdoor and indoor environments, fueling public awareness, compliance, and health protection.

As public health awareness sharpens—especially concerning respiratory and cardiovascular hazards—urban centres and industrial zones are investing in monitoring infrastructure. The rise of smart air monitoring networks, linking sensors across municipalities and industrial facilities with the Internet of Things and cloud analytics, further accelerates deployment. Additionally, indoor environments such as offices, schools, hospitals, and manufacturing sites rely on indoor air quality analytics for occupant wellness and regulatory compliance.

Governments, corporations, and communities increasingly depend on this data for policy-making, HVAC control, and emergency response. The market is projected to chart a compound annual growth rate (CAGR) of 10–12 % through 2030, with total market value expected to reach several billion USD globally.
