Indoor air has been found to be up to 70 times more polluted than outdoor air. Consequently, it is important to have an adequate ventilation system in any building. However, the ventilation system itself is only part of the solution; the other part his making sure that the system is periodically cleaned to remove allergens like mold and dust from the ducts and other components. Increasingly, facilities are having their ventilation systems cleaned due to concerns over occupant health, comfort, and safety. Additionally, more facilities are seeking this service due to the media's heightened coverage of indoor air quality problems which has led to an influx of lawsuits, and in turn increased liability for facility owners.
