Sawyer Squeeze vs Sawyer Mini: which should you carry?
Short version: get the Sawyer Squeeze for backpacking trips, especially with a partner, because it flows noticeably faster. Get the Sawyer Mini for day hikes, emergency kits and as a backup, where saving an ounce and some money matters more than speed.
Both use 0.1-micron hollow-fiber filters that remove bacteria and protozoa but not viruses. The Squeeze (SP129) weighs about 3 oz and flows faster. The Mini weighs about 2 oz and flows noticeably slower. Both backflush to restore flow, and neither should freeze when wet.

Why pick Sawyer Squeeze (SP129)?
On a multi-day trip you filter liters every evening, and the Squeeze’s faster flow saves real time and hand fatigue, especially when filtering for two.

For a day hike or emergency kit, you filter a liter or two at most, so slower flow barely matters and the lower price and smaller body win.
It also works as a straw or inline, which makes it a good backup to a main filter on longer trips.
