Expert Pick #03

Katadyn BeFree.

Collapsible 1L flask with an integrated 0.1-micron filter. The fastest-flowing squeeze filter on the market — drink directly from the source in seconds.

Katadyn BeFree

The Verdict.

9.3/ 10

Gavler Meta-Score

The fastest, most intuitive squeeze filter available. Fill and drink — no hoses, no pumping, no backflushing. Flask durability is the tradeoff. Best for day hikes and weekend trips; carry a spare flask for thru-hikes.

Global Critique

The BeFree is the best-feeling water filter to use — fill, squeeze, drink.

Backpacker Magazine

Fastest flow rate of any squeeze filter we've tested, with the easiest maintenance.

OutdoorGearLab

The BeFree's only weakness is the flask durability — carry a spare and you're set.

Section Hiker

Katadyn rates the BeFree at 2 liters per minute, and that claim holds up in real-world use — noticeably faster than a Sawyer Squeeze out of the box.
