Explanation
Indoor air quality (IAQ) refers to the presence and concentration of pollutants inside buildings. Pennsylvania homes commonly face: radon (from uranium-bearing geology), carbon monoxide (from combustion appliances), lead dust (from deteriorating paint in pre-1978 homes), asbestos fibers (from older building materials), mold (from moisture intrusion), and VOCs (from paints, adhesives, and furniture). Pennsylvania's older housing stock makes IAQ particularly important, and the Seller Disclosure form addresses several of these issues.
