Why is indoor air quality important?

Indoor environments can harbour contaminants at concentrations several times higher than those found outdoors. Poor IAQ has been linked to conditions such as:

  • Asthma and respiratory illness

  • Allergic reactions

  • Headache and fatigue

  • Eye, nose, and throat irritation

Testing helps to identify invisible risks, supports compliance with workplace safety standards, and is especially useful after renovations, flooding, or complaints of persistent odours.
