How do I know if I have an indoor air quality problem?
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. Another way is to identify potential sources of pollution, such as toxic household cleaning products, tobacco smoke, pets, pressed-wood products, combustible heaters, and many more. Also, identify 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. If you are still unsure, contact your local health department to find professionals to help you solve and identify your indoor air quality problems. AQI meters also determine the PM 2.5 content in the air.
