MSR TrailShot vs Sawyer Squeeze Water Filtration System

Which is the better buy? Side-by-side on rating, price, strengths, and watch-outs — with the published ratings we averaged to get there.

The short answer

Sawyer Squeeze Water Filtration System comes out ahead by a narrow margin (4.4 vs 4.7). The gap is mostly about Thru-hikers and backpackers who want one proven, near-permanent filter that is light, fast, and works in any configuration. — read the strengths below before deciding.

Ranked #5 in Best Backpacking Water Filters

MSR TrailShot

4.4

$62.99as of May 29

The MSR TrailShot is the pocket pump for hikers who deal with shallow, hard-to-reach water. CleverHiker rated it 4.3 of 5 and OutdoorGearLab 77, both praising its ability to draw from puddles and trickles via a hose, ideal for drought-prone trails and trail running. It is compact, has a longer filter life than the BeFree, and cleans by shaking. Pumping is more work for large volumes, so it is a personal on-the-go tool, not a group filter.

Strengths

— Pump-and-hose design draws water from shallow streams and puddles other filters can't reach
— Compact and pocketable at 5.6 oz for fast, on-the-go drinking
— Decent 2,000-liter filter life, double the BeFree and QuickDraw

Watch-outs

— Manual pumping is more effort than gravity or scoop-and-go for large volumes
— Flow of about 1 L per minute is slower than the squeeze filters
— Not designed for filling for a group

Higher ratedRanked #1 in Best Backpacking Water Filters

Sawyer Squeeze Water Filtration System

4.7

$46as of May 25

The Sawyer Squeeze is the long-running default for backpackers, and the experts still rank it at or near the top. CleverHiker makes it their overall Editor's Pick, OutdoorGearLab scores it 78 of 100, and GearJunkie names it the best thru-hiking filter. Its standout trait is a 100,000-gallon lifespan, so one filter can outlast years of trips. The pouches are weak, but the filter itself is fast, light, and essentially permanent.

Strengths

— Effectively unlimited 378,541-liter (100,000-gallon) filter lifespan, the best long-term value here
— Fast flow rate, filtering a liter in roughly 40 seconds when clean
— 0.1-micron hollow-fiber membrane removes bacteria, protozoa, and sediment

Watch-outs

— Included pouches are flimsy and prone to splitting; many upgrade to CNOC bags
— Backflushing with the included syringe is needed to maintain flow
— Cannot be allowed to freeze, which ruptures the hollow fibers

How they stack up

MSR TrailShot

Reaches shallow sources the squeeze-based Sawyer Squeeze, Katadyn BeFree, and Platypus QuickDraw struggle with via its hose and pump, and its 2,000-liter filter doubles the BeFree and QuickDraw; it is a personal pump rather than a hands-free group system like the Platypus GravityWorks 4L.

Sawyer Squeeze Water Filtration System

Outlasts the 1,000-liter Katadyn BeFree and Platypus QuickDraw filters many times over, and is lighter and more versatile than the group-oriented Platypus GravityWorks 4L; faster and longer-lived than the MSR TrailShot but with weaker stock pouches.
