Indoor air quality

Canadians spend an average of 90% of their time indoors at home, work and in recreational environments, so our indoor environment plays an important role on our health

Indoor air quality can be affected by:

  • Gases, including carbon monoxide, radon, and volatile organic compounds
  • Particulate matter, including tobacco smoke, dust, wood burning
  • Microorganisms, such as mould, bacteria and dust mites
  • Temperature and humidity

The source of air contaminants may be from the home itself,  activities carried out in the home or outside.

Improving indoor air quality

Indoor air quality can be improved by:

  • Controlling the source of air contaminants
  • Filtering the air or improving air circulation

Getting the air quality in your home assessed

There are a number of  private companies that can assess air quality in your home by:

  • Collecting samples
  • Monitoring human exposure to pollutants
  • Collecting samples on building surfaces
  • Modeling air flow inside buildings through computer programs
