The EPA suggests monitoring your health effects after a change in your surroundings. New health problems after moving, remodeling, refurnishing or performing pesticide applications could indicate 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.
