Canadians spend on average 90% of their time indoors. As our homes become more energy efficient by sealing gaps, insulating walls and installing energy efficient windows and doors, our indoor environments have less infiltration of outside air. Less air leakage into your home means that there is less air getting out as well. This is where indoor air quality can start to suffer.
Dust particles, organic materials and bacteria are always floating in the air. If the ventilation or heating system in your home is not exchanging the air or filtering in the right way, this can lead to a rise in the air pollutants within your home.
