Proper ventilation in the home can be essential to decreasing levels of indoor air pollution. Your house may be put at risk when the intake and exhaust is not in balance, causing positive or negative pressures. When a house is under negative pressure, outdoor air is forced inside. This flow causes problems such as backdrafting, or when combustion gases are pulled back down chimneys, and high levels of radon. Excess moisture in the house occurs frequently in bathrooms, so make sure to test the functioning and performance ability of your bathroom exhaust fans. Using these tips and being aware of the airflow in your home will keep the air you breathe safe for all inhabitants.
