Understanding Indoor Air Quality Issues

The quality of indoor air is a concern to energy and environmental researchers as well as consumers. Since we spend up to 90% of our time indoors in winter, maintaining a clean indoor environment is important. Consumers should become aware of how the products they bring home, such as furniture and carpeting, can affect their indoor environment. Homeowners want to use energy efficiently and reduce their fuel bills. Many have added insulation, vapor barriers, caulk and weatherstripping to their homes to effectively retain heated or cooled air and reduce air infiltration from outside. Therefore, air remains inside longer and so do pollutants within the air.

Air changes

Air infiltration rates for homes vary with the amount of weatherization, construction materials, workmanship, temperature, wind, and activities of the occupants. Infiltration rates are measured in air changes per hour (ACH), the number of times each hour that indoor air is replaced by outside air. Rates differ from house to house and from day to day. Generally, older homes have an average of one to two ACH. Tight, new homes or older homes which are sealed may replace air only once every 3 hours or more (or .35 ACH). Be aware of these signals which may indicate poor indoor air quality:

  • “stuffiness”
  • frequent head or chest colds
  • mold or mildew
  • a musty smell or lingering odors
  • heavy condensation or frost on windows
