Primary Sources of Indoor Air Pollution

The word pollution is often associated with large clouds of smoke emerging from factory smoke stacks, automobiles, etc.

In fact, the majority of people blame poor indoor air quality on outdoor air pollution.

But this is not not true ! 

Outdoor air pollution only counts for a fraction of indoor air pollution.
