Grayl Geopress vs MSR Thru-Link In-Line Microfilter

Switchback Travel, a review site with a history of doing objective hands-on testing, has great things to say about the MSR Thru-Link In-Line Microfilter. In fact, it's "Best Inline Filter for a Hydration Reservoir" in its "Best Backpacking Water Filters of 2023" roundup, which points toward it being a good Backpacking Water Filter.

As for the Grayl Geopress analysis - it impressed reviewers at Gear Patrol, a source that's known for its objective testing and well-thought-out methodology - it performed great in its "The 6 Best Purifying Water Bottles for Travel" roundup and earned the "Ranked 1 out of 6" title.

As a last step, we wanted to do a head-to-head MSR Thru-Link In-Line Microfilter vs. Grayl Geopress comparison of their review performance but, unfortunately, weren't able to find any review ratings on either product.
