Causes of Indoor Air Pollution

Indoor air pollution can come from a number of hidden sources. One deadly form comes from mixing cleaning compounds such as ammonia and bleach. This creates toxic gas that can kill. "Bug bombs" can also be a nasty source indoor air pollution, as they can leave traces of poisons, which can be stirred up by sweeping, vacuuming, and other household activity.

Hanging drywall, grinding, sanding, or paint scraping will leave dust and residue that must be dealt with. Otherwise it, too, can be stirred up and inhaled with ordinary activity in the home. Indoor air pollution isn't always as obvious as it sounds. Sometimes it lies in the corner, waiting to be stirred up and kicked into the otherwise healthy air.
