Why Indoor Air Quality Matters
According to the EPA, Americans spend approximately 90% of their time indoors, where air pollutant concentrations can be 2 to 5 times higher than outdoor levels. Poor indoor air quality (IAQ) can cause immediate health effects like headaches, fatigue, and respiratory irritation, as well as long-term problems including respiratory disease and cancer.
Michigan's climate, which keeps us indoors much of the year, makes indoor air quality particularly important for residents.
Common Indoor Air Pollutants
Several categories of pollutants can affect indoor air quality. Biological Contaminants include mold and mildew, dust mites, pet dander, bacteria, and viruses. Michigan's humidity levels make biological contaminants a common concern.
Chemical Pollutants include volatile organic compounds (VOCs) from paints, cleaners, and furnishings, formaldehyde from building materials, carbon monoxide from combustion appliances, and tobacco smoke.
Particulate Matter includes dust, pollen, and fine particles from cooking, heating, and outdoor sources.
Gases include radon (a significant concern in Michigan), carbon dioxide from occupants and combustion, and combustion byproducts.
Signs of Poor Indoor Air Quality
You might have IAQ problems if occupants experience headaches, fatigue, or difficulty concentrating, respiratory symptoms worsen when indoors, there are musty or chemical odors, condensation appears on windows or walls, or dust accumulates quickly after cleaning.
Indoor Air Quality Testing Methods
Professional IAQ assessment may include several types of testing. Air Sampling captures airborne particles and analyzes them for mold spores, bacteria, allergens, and other contaminants.
VOC Testing measures volatile organic compounds using specialized equipment or laboratory analysis.
Carbon Dioxide Monitoring indicates ventilation adequacy—high CO2 levels suggest insufficient fresh air.
Radon Testing measures this radioactive gas that's common in Michigan homes.
Humidity and Temperature Monitoring assesses conditions that affect comfort and mold growth potential.
Improving Indoor Air Quality
Based on testing results, improvements might include source control by removing or reducing pollution sources, improved ventilation through mechanical systems or natural airflow, air cleaning using filtration or purification systems, and humidity control to maintain 30-50% relative humidity.
When to Test Indoor Air Quality
Consider IAQ testing when occupants have unexplained health symptoms, after water damage or flooding, before and after renovation projects, when buying or selling a home, in buildings with known ventilation issues, and as part of regular home maintenance.
The Role of Professional Testing
While home test kits exist for some pollutants, professional testing provides more accurate results, comprehensive assessment of multiple factors, expert interpretation of findings, and specific recommendations for improvement.
