Common Residential Air Quality Problems in the Pacific Northwest

  • Mold: Humidity is one of the greatest challenges in western Oregon homes. It can be caused by moisture-related issues, the way a building is used or relative humidity levels.
  • Carbon monoxide: A tight building envelope is good when it comes to saving energy. Without sufficient ventilation, it can lead to a dangerous buildup of carbon monoxide.
  • Chemicals: Products like air fresheners, cleaning products, paint, pesticides, smoke, perfume, hairspray, nail polish and other common household items release chemicals into the air.
  • Off-gassing building products: Several items in a home can release gasses into a home, including plywood, particleboard, dryer sheets, acetone, laser printers, wall paint, new carpeting and new furniture.

Troubleshooting Indoor Air Quality Problems

Things that seem like an inconvenience might actually symptoms of air quality issues:

  • The house is dustier than usual: If your home has an HVAC system with ductwork, change the air filter. If that doesn’t help, the ductwork might have a leak or need cleaning.
  • The home seems more humid than usual: A leak in the ductwork may be to blame. Some HVAC problems can also make a home feel more humid.
  • The development of cold- or allergy-like symptoms: Dizziness, nausea, fatigue, difficulty breathing, asthma flare-ups, respiratory ailments, or irritation of the nose, eyes or throat are signs of air quality issues.
  • Sick building syndrome: If a member of the household experiences one of the symptoms listed above and feels better after leaving the home, this may be a sign of poor air quality.
  • Observation and elimination: Notice if individuals in the home feel sick in certain areas of the home, at certain times of the day or at certain temperatures. Then try different ways to remedy the problem. For example, of an individual feels ill in a bathroom with an air freshener, remove the air freshener. If people feel sick in a stuffy room, open a window to see if symptoms resolve.
