A lot of mold spores sit quietly on surfaces until something disturbs them. Disturbance testing takes advantage of that by intentionally agitating a suspect area, like tapping a wall, shaking an HVAC filter, or moving insulation, and then immediately collecting an air sample. This gives a much more realistic picture of what someone might actually breathe in during everyday activity or during construction and renovation work.
