J67.7: Air-conditioner and humidifier lung

Air-conditioner and humidifier lung, medically referred to as hypersensitivity pneumonitis, is a type of lung disease caused by an exaggerated immune reaction to airborne particles. These particles could be breathed in from various environments, but in this particular case, they mainly come from air-conditioners and humidifiers. When you inhale these particles, your body's immune system may overreact, causing inflammation and damage to the lungs. Symptoms vary from person to person but often mimic those found in other respiratory illnesses, such as shortness of breath, coughing, and fatigue. It could potentially lead to more serious lung diseases with chronic exposure. This condition does not spread from person to person but depends on individual immune responses to certain airborne substances commonly found in air-conditioners and humidifiers.
