If you're like most Americans, you spend much of your tim eindoors. Have you ever stopped to think about whether the air you're breathing at hiome is healthy? When you're at home do you frequently have headaches or feel nauseous or tired? Do you feel better when you leave the house? If you have these symptoms, or others listed in this booklet, your home's air quality may be the problem.

Recent research has found that in homes across America, the quality of indoor air can be worse than outdoor air. That's because many homes are being built and remodeled tighter - some with improved ventilation system to provide fresh air exchange. We are using more products and furnishings containing compounds sensitive to some occupants.

You don't have to be a building scientist to deal with the quality of air in your home. However, you should understand a few basics. to get you started. The "Healthy Indoor Air for America's Homes" project was developed to provide basic but comprehensive information to consumers to get a handle on indoor air quality.

A major hazard is MISINFORMATION. Be informed. Request more information by contacting the resources listed on the back of this booklet.
