Ask the home inspector – Air Quality
Q: What causes poor indoor air quality?
A: Indoor pollution sources that release gases or particles into the air are the primary cause of indoor air quality problems in homes. High temperature and humidity levels can also increase concentrations of some pollutants.
Indoor air pollutants range from minor irritants such as dust and animal dander, to major irritants such as moulds and chemical vapours that may be emitted from building materials and furnishings. Inadequate ventilation can increase indoor pollutant levels by not bringing in enough outdoor air to dilute emissions from indoor sources and by not carrying indoor air pollutants out of the home. 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.
