**What Exactly Are We Breathing Indoors?**

Indoor air pollution is a complex mixture of particulate matter and gases from a startling variety of sources. Unlike outdoor pollution, which disperses, these contaminants are trapped and recirculated, creating a concentrated environment. The culprits fall into several key categories.

* **Combustion Byproducts:** This includes carbon monoxide from faulty heaters, nitrogen dioxide from gas stoves, and even particulate matter from fireplaces and candles.
