Many years ago I bought a Safewater Anywhere hydration system,used it a bit, then put it away in favor of a Platypus system. After dusting it off last spring, I planned to use it and was told by a hiking friend that this particular filter was recalled some years ago. *I* think Safewater stopped making them because the company was bought out. One might think that the recall could be searched out via Google or some such. I have had no luck finding anything, so am turning to the "community" to see if anyone has information one way or another.
