Every year in the month of May, the American Lung Association designates Clean Air Month in order to bring attention to the importance of breathing clean air. For many people, this is something that they take for granted. But for those with asthma or other respiratory illnesses, it can be a matter of life and death. Homeowners can play a role in promoting clean air by taking steps to reduce pollution from sources like vehicle exhaust, power plants, and factories. Additionally, homeowners can help to reduce the number of airborne particles in their homes by vacuuming regularly, dusting with a damp cloth, and avoiding the use of aerosols and other chemicals. By making an effort to improve air quality both inside and outside the home, everyone can breathe a little easier during Clean Air Month- and every month after that.
