The first rule for a healthy home is to control indoor pollutants at their source. If pollutants aren’t created or brought into the house in the first place, you won’t need to get rid of them.
Sources of indoor pollutants include toxic household cleaning supplies, furniture, new carpets, paints and finishes, cabinets, cosmetics, smoking, pets, car exhaust, and pests. Many furnishings and interior finish products outgas (or off-gas) pollutants, sometimes for several months or years.
Combustion appliances—those fueled by propane, natural gas, kerosene, oil, or wood—are another source of indoor pollutants. They produce toxic gases and tiny particles that pollute indoor air. Unvented combustion appliances, such as a gas range or an unvented space heater, can have ventilation added to reduce the concentration of pollutants. Combustion appliances that have a chimney or a vent pipe can also cause trouble if the exhaust air is sucked back down into your living space.

Ventilation can improve your indoor environmental quality, but many indoor air pollutants need to be addressed more directly. Check out the following resources to help keep you and your family safe.
