How to Breathe Better Air

Americans spend nearly 90 percent of their time indoors, making indoor air quality critical, as experts at the American Society of Heating, Refrigerating and Air-conditioning Experts emphasize that ventilation and HVAC system performance directly influence the air people breathe.
According to the Asthma and Allergy Foundation of America , over 28 million Americans have asthma, and eight out of ten people are exposed to dust mites, a common indoor allergy trigger that can worsen respiratory symptoms.
Dirty filters restrict airflow and allow particles of dust, pollen, and pet dander to recirculate throughout homes via HVAC systems, compounding indoor air quality problems and health risks for residents.
Homeowners can manage these pollutants by changing air filters regularly, maintaining proper bathroom and kitchen ventilation, and controlling household humidity to reduce mold growth and indoor air concerns.
Qualified professionals with the National Air Duct Cleaners Association can evaluate and improve HVAC system performance, particularly when visible buildup near vents signals the need for professional inspection and maintenance.
