MSR has announced its newest development in safe water, the Thru-Link In-Line Microfilter. For users that carry a hydration reservoir system, the Thru-Link is the ideal light and simple-to-use filter that quickly connects into any reservoir for filtering on the go.

The Thru-Link Filter is simple, lightweight, and eliminates the need for excessive gear in the backcountry. It features no moving parts and is compact, making it easy to pack for any length of adventure, from a single day hike to a weeks-long backpacking trip. In addition to providing in-line filtration as a drink-through filter on the trail, the Thru-Link can be used as a gravity filtration system by your hydration reservoir at camp.

The Thru-Link meets NSF Protocol P231 for the removal of bacteria and protozoa. Its two-stage filtration chamber includes fast-flow hollow fiber for the removal of pathogens, particulates, and microplastics, and activated carbon that reduces chemicals, tastes and odors. Like all MSR filters, the Thru-Link is tested by MSR’s on-site, world-class water research laboratory at the company’s Seattle factory headquarters.

Originally developed as an on-the-move water filtration solution for the U.S. military in the early 2000s, the Thru-Link has been in use by service members for more than a decade. Recognized for its durability, speed, and effectiveness, more than 360,000 Thru-Link Filters have been used by the military since 2006. The filter becomes available to outdoor recreationalists starting in February 2020.
