How Do we improve the air quality in our Homes?

 Usually the most effective way to improve indoor air quality is to eliminate individual sources of air pollution or to reduce their emissions. Some sources, like those that contain asbestos, can be sealed or enclosed; others, like gas stoves, can be adjusted to decrease the amount of emissions. In many cases, source control for air quality is also a more cost-efficient approach to protecting indoor air quality than increasing ventilation because increasing ventilation can increase energy costs.

Most home heating and cooling systems, including forced air heating systems, do not mechanically bring fresh air into the house. Opening windows and doors, operating window or attic fans, when the weather permits, or running a window air conditioner with the vent control open increases the outdoor ventilation rate and serves as a simple form of air cleaners. Local bathroom or kitchen fans that exhaust outdoors remove contaminants directly from the room where the fan is located and increase the outdoor air ventilation rate.

It is particularly important to take as many of these steps as possible while you are involved in short-term activities that can generate high levels of pollutants–for example, painting, paint stripping, heating with kerosene heaters, cooking, or engaging in maintenance and hobby activities such as welding, soldering, sanding, model making and gluing.

However, remember that for most indoor air quality problems in the home, source control is the most effective solution.
