Ventilation of our homes should be simple and effective. It is an essential requirement in homes to provide clean air for breathing and to dilute moisture, odours and pollutants arising from everyday activities such as drying laundry, cleaning, bathing and cooking. In the drive for energy efficiency house design has changed and, as our homes become better-insulated and more draught proof, it is now even more important that we all understand how to ventilate our homes adequately.

However recent research undertaken by MEARU in a variety of social rented, affordable and private dwellings in Scotland has shown that dwellings are not being adequately ventilated. This can negatively affect indoor air quality and the health of the occupants. This unique film is a free online resource for housing providers and occupants that aims to raise awareness of ventilation and demonstrate how it can be achieved.
