    Any more information on patents? Which countries?

    – Note: US EPA doesn’t actually “approve” products like this. They can be tested
    against a guide standard protocol (link to document here: http://www.biovir.com/Images/pdf06..., and products or manufacturers can be
    listed with EPA, but that’s not exactly the same as EPA “approving”
    their performance or use.

    There are many research papers that have documented the performance of the PUR/P&G Purifier of Water packets – although not the full system shown here. Some of these are listed below, in no particular order:
