Breathing clean air indoors is crucial for maintaining optimal health and well-being, even when individuals are exposed to polluted air outdoors. While outdoor air pollution is a significant concern, ensuring clean indoor air is essential because people spend a considerable amount of time indoors, where indoor pollutants can accumulate and pose health risks. Poor indoor air quality can exacerbate respiratory problems, allergies, and other health issues, particularly for vulnerable populations such as children, the elderly, and those with pre-existing conditions. By prioritizing clean indoor air through proper ventilation, air filtration systems, and reducing indoor pollutants, individuals can mitigate the adverse effects of pollution on their health and create a safer and healthier indoor environment.
