Can indoor air be hazardous to your health?

Absolutely. Air pollution levels can be nearly 100 times greater inside than outdoors. The American Lung Association says that many people spend 90% of their time inside, making it critical for homeowners to be knowledgeable about indoor air quality (IAQ) in Canada.

Many common household items cause bad indoor air quality, such as:

  • Chemicals used in carpet, furniture, upholstery and drapes
  • Cleaning chemicals
  • Paint
  • Personal care products

The tight construction of today's residences also contributes significantly to poor IAQ. Upgrades like weather stripping and storm doors are created to decrease heating and cooling expenses. However, they also prevent proper ventilation by keeping inside air in and outdoor air out. The result could be an accumulation of fumes within your house.

Bad IAQ can be a direct or indirect source of several health issues. Medical groups have determined that up to half of all ailments are linked or irritated by indoor air pollution.

Chemicals within your house can result in flu-like illness like headaches, nausea and respiratory sensitivity. It can also worsen allergies and asthma.

Enough ventilation also is an important part of bettering indoor air quality, since it reduces the amount of indoor pollutants.
