Learn more about indoor air quality
The Lung Association offers in-depth indoor air quality resources.
Most people are aware that outdoor air pollution can damage our health, but fewer realize that indoor air pollution can be as or even more harmful.
Because Canadians typically spend close to 90 percent of their time indoors, there is considerable public health concern about the health effects of indoor air quality. It has been shown to cause and/or exacerbate a wide array of health effects: allergies; asthma; lung cancer; respiratory infections such as bronchitis and pneumonia; ear, nose, and throat irritation and inflammation; COPD; and many others.
