LifeSaver Jerry Can

Someone told me about a new water filtration product a few weeks ago, and apparently I forgot to store the info away for future recall.  It's the LifeSaver Jerry Can, which supposedly has 15nm pores, which would make it a purifier, more or less.  However, some viruses apparently get down to 4nm, so even this isn't 100%.  This filter was discussed in a TED talk.
