The air you breathe is one of the most significant and least chosen environmental health determinants — indoor and outdoor air quality affect lung function, cardiovascular health, cognitive performance, sleep, and all-cause mortality in ways that decades of epidemiological research have made clear. Indoor air is often worse than outdoor air, and improving it through ventilation, filtration, and reducing sources of pollution (cooking fumes, off-gassing materials, mold) is one of the highest-impact environmental health interventions available at home. For the approximately one billion people globally living with respiratory disease, air quality is not an abstraction but a daily clinical reality.
