MSR’s Thru-Link Inline Microfilter is a field-proven, simple solution to getting clean water on the go. Setup is straightforward, just click it into your hydration system, and the Thru-Link will filter water as you drink. Match-made for fast-paced hiking, the high flow rate enables you to stay hydrated with ease. Featuring a two-stage filtration, the hollow fibre technology removes pathogens, particulate and microplastics, while activated carbon reduces chemicals, tastes, and odours. Lightweight, practical, and versatile, when you're back at basecamp the Thru-Link enables your reservoir to do double-duty as a gravity system.
