We spend most of our lives indoors so we should give more thought to the air quality in our sheltered environment. There are gases and fumes that we can’t see or smell but are extremely toxic. This includes radon, carbon monoxide, mold, and VOC’s (Volatile Organic Compounds). Early detection and prevention after the jump.
Check out the EPA’s recommendations for indoor air quality. There is also the Indoor Air Quality Association which is a non-profit group that is focused on indoor air quality education.
