Can you put water filters on any DVC unit kitchen faucets? I know that at the VWL and BCV they have goose neck faucets that look pretty standard. I'm just not sure if you can remove the screen part - or if it would remove easily. Has anyone ever used either the Brita or Pur filter systems? The box says "no tools necessary" but I'd hate to be stuck without filtered water. We usually bring our Brita pitcher but I'd sure like to save some room in our luggage.
