Pulmonology is a medical field of study within internal medicine that focuses on the respiratory system. If you’re experiencing breathing issues or have a concern about your lungs, windpipe, or any part of your respiratory system, a pulmonologist is the type of physician you’ll want to see. Some pulmonologists specialize in certain diseases and conditions, like asthma, pulmonary fibrosis, and chronic obstructive pulmonary disease (COPD). Pulmonologists frequently work with cardiologists to diagnose patients because lung and heart conditions can present similar symptoms [1].

According to the Asthma and Allergy Foundation of America (AAFA), people spend more than 90% of their time indoors, and indoor air can be two-to-five times more polluted than outdoor air. Indoor air quality plays a critical role in asthma management, as common household pollutants like dust, pet dander, mold, pollen, and volatile organic compounds (VOCs) are common triggers for asthma symptoms [2].

Dirty air can either cause or worsen respiratory symptoms, including coughing, difficulty breathing, and upper airway congestion. Pulmonologist Rachel Taliercio, DO explains how indoor air purifiers can promote health: “Airborne toxins are irritants. … To the extent that you could eliminate some of those particles in the air and reduce the exposure, you’re going to reduce effects on health.” Air purifiers are especially beneficial to young children, elderly people, and people living with heart and/or lung disease, for example, cystic fibrosis and conditions of the immune system [4].
