Indoor Air Quality

The need for clean air in our homes should not be underestimated. Canadians spend an average of 90% of their time inside; and our homes contain many substances that may be hazardous to our health. Indoor air pollutants range from minor irritants such as dust and animal dander, to major irritants such as molds and chemical vapours that may be emitted from building materials and furnishings. It is important to be aware of how air contaminants can affect our health and to adopt corrective measures that will improve indoor air quality in our homes.
