Clean water is non-negotiable on the trail. A good filter is light, fast and simple. Here are the water filters we trust for hiking and backpacking in 2026.
1. Sawyer Squeeze — Best overall
Tiny, light and effectively lifetime-rated for hundreds of thousands of litres. Screws onto most bottles or a squeeze pouch — the default choice for most hikers.
2. Katadyn BeFree — Best for fast flow
A collapsible flask with a wonderfully fast flow rate and easy field cleaning. Perfect for quick sips on the move.
3. Platypus QuickDraw — Best for versatility
Fast flow, easy backflushing and compatible with standard bottles. A strong all-rounder and simple to maintain.
4. LifeStraw Peak Series — Best budget
Affordable, durable and versatile — drink direct, use inline, or as a squeeze filter. Great value for occasional hikers.
5. MSR Guardian — Best for expeditions
A rugged pump purifier that removes viruses as well as bacteria and protozoa. Overkill for weekend trips, ideal for international or high-risk sources.
