Product Details
A hands-free water purifier for the times you need the highest level of protection—international travel, questionable sources, or filling for a group. Where most backcountry filters stop at bacteria and protozoa, the Guardian's 0.02-micron hollow-fiber cartridge also removes viruses, plus sediment and microplastics, and a second activated-carbon stage cuts chemicals and improves taste. You fill the 10-liter reservoir at a stream or a sink, hang it, and let gravity do the work while you handle other camp chores. There's no backflushing to fuss with—opening the purge hose flushes the system and keeps the flow rate up. It's built rugged (originally designed for military use), so it shrugs off the abuse of travel and packs down for a carry-on or a smaller pack.
