Is this new?

Have I been living under a rock? Did I miss the product introduction? Are those things an old trick? Are such gizmos made by other people than MSR « makers of fine overpriced gear »?

My fear of beaver fever is somewhat smaller than my lazyness, but this could be a compromise: although the 4h sit-time to kill cryptosporidium is impractical, since it seems quite efficient for large volumes, it could be great for flat water canoe tripping.

Wait, my wallet is thinner than both the fear and the lazyness. I’ll hang on to the Polar Pure.
