This one’s for the folks who are doing some arduous hiking. If you’re confronted with some murkier water sources and need a heavy-duty solution, the MRS Guardian Purifier is a perfect choice. This backpacking water filter is the winter of BackPacker Magazine 2016’s editor’s choice award for a reason. Its advanced medical-grade fibers block viruses and physically remove viruses, bacteria, protozoa, and particulates. This level of purification is something that most hollow-fiber filters cannot achieve. It’s also perfect for cold-weather hikers, since it’s engineered to withstand freezing temperatures.

In just a few minutes, this system will produce about 4 liters of purified water. Using hollow fiber as its purifying mechanism, this backpacking water filter eliminates protozoa, bacteria, particulate, giardia, E. coli, salmonella, and more.
