Indoor Air Pollution

Poor indoor air quality (IAQ), or indoor air pollution, occurs when there is a build up of pollutants in the home to the extent that it affects the occupant’s health and comfort.

We spend 90% of our time indoors and around 16 hours a day in our homes. Indoor air can be up to 50 times more polluted than outdoor air and contain up to 900 potentially dangerous chemicals and particles. As homes are becoming more air tight, there is a greater chance that pollutants will accumulate, thus creating a higher health risk.

The My Health My Home campaign aims to raise awareness of the impacts of poor IAQ on health, promote effective ventilation as a means of managing IAQ, and ensure that good IAQ is a serious policy consideration in public health and building policy.
