According to Study Findings
- Particle count readings were higher during cleaning than before or after cleaning. This suggests dirt, debris and other pollutants may become air- borne as a result of disturbances caused by the cleaning processes. (See fig. 4).
Readings are average of 15 minutes readings.
- Cleaning procedures were not found to have contributed to a higher indoor fiber count. Thus, the concern that cleaning fiber glass ductwork using these methods might increase the amount of fibers in the house is not supported by the findings of the study. (See fig. 5).
- Homes cleaned with the Air Sweep method showed the greatest reduction in bioaerosol concentration.
