Adding minimal weight to your pack, the MSR Thru-Link In-Line water filter clicks into your hydration reservoir and makes it easy to stay hydrated on long day hikes and fast-paced missions.

  • Features

    • Engineered for high-flow, easy drinking—no need to stop and filter; just scoop and go
    • At camp, the Thru-Link lets you use your reservoir as a gravity system for the luxury of pump-free filtration
    • 2-stage filtration: Fast-flow hollow fiber removes pathogens, particulate and microplastics; activated carbon reduces chemicals, tastes and odors
    • Combination of hollow-fiber technology and activated carbon is effective against bacteria (99.9999%), protozoa (99.9%) and particulate (dirt, microplastics)
    • Quick-Connect system makes this compatible with any hydration reservoir system on the market
    • Used by the U.S. military for more than a decade; rugged ultrasonic welded housing provides reliable durability
    • Meets U.S. EPA drinking water standards and NSF protocol P231 testing standard for removal of bacteria and protozoa
