Abstract
Abstract According to an exemplary embodiment of the present disclosure, a method of loading a filtering device includes measuring a metric indicative of an initial loading of the filtering device and desirably positioning a quantity of matter proximate the filtering device. The method also includes applying a negative pressure to the filtering device such that at least a portion of the quantity of matter is drawn into the filtering device. The method further includes measuring a metric indicative of a final loading of the filtering device.
