PT knows the weight of the carbon in the filter. In shipping terms, it would be part of the "Tare" along with the weight of the container. The assay samples the PM-laden carbon, measures the amount of each and assumes homogeneity of the mixture in the filter.

The weight of the container and carbon only matter for shipping charges. Think of a box of cereal. They often have a notation that the product is sold by weight, not volume so you won't complain about a 2/3 empty box. However, the price/ounce you pay is for the "net weight", not the weight you would see if you put the box on a scale.
