Are you worried about the air you breathe? Don't assume you're safe just because you're inside. The Environmental Protection Agency (EPA) says that the air within homes and other buildings can be more seriously polluted than the outdoor air in even the largest and most industrialized cities.
Indoor air pollution can have significant health problems. People who may be exposed to indoor air pollutants for the longest periods of time -- children, elderly adults and people with chronic illnesses -- are often those most susceptible to the effects of indoor air pollution.
Most indoor air pollution comes from sources that release gases or particles into the air. Sources such as building materials and air fresheners release pollution continuously. Other sources such as tobacco smoke and wood-burning stoves are related to activities. Although some indoor air pollutants have been around for years, they often were diluted by outdoor air seeping into the home. Today's more energy-efficient homes don't allow as much outdoor air to enter.Learn how indoor air can cause health problems ›
