Sorry but no, maybe you're buying the value brand carbon scrubbers where that may actually be the case, but the quality brand name scrubbers are filled to the tits.
manufacturers use industrial shakers, a car ride does not equal an industrial shaker.
My scrubber, I can roll around, flip it end to end, the carbon within does not move.
IF you were right, and the carbon settles during shipping there would be airspace within the canister after the shipping process. Rolling the scrubber would reveal such.
+1 to that. My first carbon scrubber was an Ebay special. It worked OK for a while, but you could definitely hear the carbon shifting around inside. The latest filter I bought has zero noise of carbon moving around while shaking it, must be packed really tight in there.
