Powdery activated carbon from brewhaus

Does the activated carbon available from places like brewhaus.com have fine particulate matter? I've sourced some carbon locally but I suspect (based on a small sample) it is too powdery. After rinsing the stuff rigorously my filtered spirits have a sight grey tinge and fine particles are obviously visible even after being passed through a couple of coffee filters.
Reason I ask is that I'll just go ahead and order locally if I'm going to have to deal with that anyways.
And while I'm at it, is it normal to see a drop of ABV after filtering? I just had some 40% swishing around in a jug with the carbon for a week or two. Today it was 30%. Tasted like watered-down bottom shelf vodka. Damnedest thing.
