Indoor Air Quality & Exposure

The quality of the air inside our homes, schools and workplaces matters, particularly since we spend most of our lives indoors. Sources of indoor air pollution include building materials, gas appliances, cleaning products, personal care products and furniture.

CARB is actively involved in the development of green building standards and indoor air quality guidelines. CARB also regulates indoor air cleaners so that consumers can be assured of their safety. CARB also sponsors and conducts research into all aspects of indoor air quality, with a focus on determining levels of exposure to harmful indoor air pollutants, and seeking ways to prevent and reduce that exposure.
