Whether you live in an apartment, townhome or single family home, an old home or are building a new home, there are many ways to protect and improve your indoor air quality.

Indoor pollution sources that release gases or particles into the air are a primary cause of indoor air quality problems in homes. Inadequate ventilation can increase indoor pollutant levels by not bringing in enough fresh outdoor air to dilute emissions from indoor sources and by not carrying indoor air pollutants out of the home. High temperature and humidity levels can also increase concentrations of some pollutants.

The resources on this page will help you take immediate steps to protect IAQ in your home and prevent IAQ problems during remodels, renovations or when building a new home. You can also find resources to help building professionals and residents protect IAQ in multifamily buildings.
