With the water filtration battle heating up, it’s time to pit two of the top contenders against one another and determine who will reign as heavyweight champion. It’s going to be a battle royale. In the blue corner, weighing in at 13 oz., is the LifeStraw Mission five-liter water filter. The LifeStraw Mission is a high-volume, gravity-powered water purifier that removes viruses in addition to bacteria and protozoa to make backcountry water safe to drink.
In the red corner, weighing in at a scant 10.5 oz., is the MSR AutoFlow Microfilter. Now with an even lighter filter cartridge, the AutoFlow Microfilter represents the latest evolution of backcountry hydration, combining filtration, storage, and collection into a single, pump-free system.
