I was amused by that, too - the local outfitter had both, and I couldn't tell any difference at all in the filter itself (except the label - kind of like the way Chevys and Pontiacs only differed by the insignia for a while.) The big difference was in the containers (Platys v. Dromlite-like bags. The Platypus seemed a bit easier to use.

Using the pot works, too - except that I have to dig the pot out of my pack. (The filter lives in a side pocket on the outside of the pack.) I thought you might have one of those elegantly simple solutions that would make me slap my forehead and go "Doh!!" in true Homer Simpson fashion.
