How has the air quality sensors market evolved, and what factors have shaped its growth?

The increasing number of airborne diseases and fatalities is expected to propel the growth of the air quality sensors market going forward. Airborne diseases refer to bacteria or viruses that primarily spread through tiny respiratory droplets. The growth of airborne diseases is influenced by various factors, such as higher population density, international travel and migration, and the emergence of antimicrobial-resistant strains. Air quality sensors are used to detect airborne pollutant concentrations, as these devices are engineered to identify and display levels of a specific pollutant, such as particulate matter (PM), within indoor environments. For instance, in November 2023, according to the Centers for Disease Control and Prevention, a US-based government agency, there was an 18% increase in the estimated number of cases and a 43% increase in the estimated number of deaths of measles in 2022, compared with an estimated 7,802,000 cases and an estimated 95,000 deaths in 2021. Therefore, the increasing number of airborne diseases and fatalities is driving the growth of the air quality sensors market.
