The American Lung Association offers these suggestions to help keep the air clean at home:

• Don't allow smoking in the home.
• Have your home tested for radon gas.
• Make sure your home's humidity level is below 50 percent. Install a dehumidifier if humidity levels are too high.
• To prevent attracting mold, make sure no plumbing is dripping or leaking.
• Keep trash covered and food securely stored to ward off pests.
• Avoid using candles or sprays to hide odors.
• Avoid using household products that contain toxic chemicals.
