(HealthDay News) -- If the air inside your home is stagnant and doesn't get replaced very often, the indoor pollution that results could worsen symptoms of allergies, asthma, or other chronic lung problems.

The U.S. Environmental Protection Agency suggests how you can improve indoor air quality at home:

• Improve emissions or eliminate entirely sources of indoor air pollution, such as wood-burning stoves.
• Modify air conditioning or heating systems to allow intake of more air from the outside.
• Use exhaust fans to push contaminated air out of the home.
• Use an indoor air-filtering device.
