The EPA suggests monitoring your health effects after a change in your surroundings. For example, if you have new health problems after moving, remodeling, refurnishing, or a performing pesticide application, this could be an indicator of an indoor air quality problem. Consult your family physician.

Other sources of indoor air quality problems include: 

·Toxic household cleaning products

·Pets

·Pressed-wood products

·Poor ventilation

Look for smelly or stuffy air, condensation on walls or windows, or mold growth around your home.
