Australian homeowners are increasingly keeping their windows closed due to noise, pollution and security. This reduces healthy natural ventilation and can increase the inhalation of harmful pollutants and respirable dust.
Modern homes are well insulated and sealed tight to increase energy efficiency, but are more likely to have poor ventilation because they cannot breathe. Opening doors and windows is not always practical and does not provide adequate ventilation, which needs movement and exchange of air.
Off-gassing of paints, floor coverings and building materials creates an unhealthy environment indoors. In fact, the air inside our home is 4 times more polluted than the air outside our home, meaning that 50% of toxic substances we are exposed to will come from inside our homes.
Pollutants in our homes range from carbon dioxide (from breathing), carbon monoxide (from cooking and unflued gas heaters), Volatile Organic Compounds (VOCs) and formaldehyde (from building materials), mould, pollen and dust mites.
