The Water Filter: MSR SweetWater Purifier System

By Nathan Borchelt & Caitlin Thompson

When it comes to prepping something as essential as drinking water, it's best to keep things simple. And with the 14-ounce SweetWater filter, that's exactly what you get. Drop the black tube's pre-filter into the water, attach the clear tube to the water-bottle adapter (slotted to fit everything from a wide-mouth Nalgene to Polar Springs bottles), and start pumping. One minute later you've got 1.25 liters of bacteria-, iodine-, parasite-free water without feeling like your arms endured an aerobic workout in the process. The other goods in this kit—a cleaning brush, storage sack, flexible two-liter Platypus bottle, and bottle of SweetWater Purification Solution, a chlorine-based purifier that rids water of viral contaminants—makes this the most complete water treatment system out there. All that's left is working up that thirst.
