According to the EPA there are three steps to improving air quality in the places you live and work. First identify potential pollution sources, whether it’s a gas stove or household cleaners under the sink. Then, provide better ventilation by opening windows or using outside vents. Be sure to keep all polluting activities like using toxic adhesives or kerosene heaters outdoors with good ventilation. Lastly, use air cleaners if necessary to rid the air of gaseous pollutants.

The EPA website lists sources of indoor air pollution (http://www.epa.gov/iaq/ia-intro.html) as well as information and resources for your region (https://www.epa.gov/indoor-air-quality-iaq/epa-regional-office-and-state-indoor-air-quality-information).
