The rising respiratory illnesses are expected to propel the growth of the smart indoor Co2 control market going forward. Respiratory illnesses affect the lungs, airways, and throat, impacting normal breathing. Their prevalence is rising due to air pollution, which causes inflammation, lowers lung function, and increases infection risks. Smart indoor CO2 control is beneficial for respiratory illnesses, as it helps maintain optimal indoor air quality, reducing the buildup of pollutants and allergens that can trigger respiratory symptoms and worsen conditions such as asthma or bronchitis. For instance, in October 2024, according to the World Health Organization, a Switzerland-based intergovernmental organization, around 8.2 million individuals were newly diagnosed with tuberculosis in 2023, marking a significant rise from the 7.5 million cases recorded in 2022. Therefore, the rising respiratory illnesses are driving the growth of the smart indoor Co2 control industry.Key Players In The Global Smart Indoor Co₂ Control Market
