EPA studies indicate that air levels of indoor pollutants may be two to three times higher than outdoor levels. Mold is a growing concern. Many people spend as much as 90% of their time indoors and are not aware of the health hazards created by this pollutant.

Mold, the most dangerous offender of all, often goes undetected because of its invisibility.
