The air inside your house is often over-used, because fresh air gets in only when you open doors or windows. Since todays homes are made more energy efficient, indoor air quality deteriorates and homes get suffocated soon. And because natural air-flow is restricted, these homes have to struggle hard to breathe.

There are many origins to these pollutants and some of these like molds give more trouble if the humidity levels are high in the house.
