How do I know if I have an indoor air quality problem?

The Environmental Protection Agency 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.

Another way is to identify potential sources of pollution, such as toxic household cleaning products, tobacco smoke, pets, pressed-wood products, combustible heaters…

Check areas of your home that may have poor ventilation. Look for smelly or stuffy air, condensation on walls or windows, or mold growth around your home.
