Drink straight from the beck. Safely.

The Portable Straw Water Filter is the simplest bit of kit in your rucksack: dip one end in the stream, tarn or dodgy campsite tap, drink from the other. No pumping, no waiting, no tablets that taste of swimming pool.

What it removes

The hollow-fibre ultrafiltration membrane strips out up to 99.9999% of waterborne bacteria and protozoa, including E. coli and Giardia, along with sediment and the peaty tang you get from Highland water. Taste is left alone, so the water comes through clean and neutral.

Why it earns a place in every pack

• Pocket-sized and lighter than a chocolate bar, so it lives in the lid of your rucksack and you forget it is there until you need it
• Nothing to charge, no moving parts, nothing to go wrong halfway up a hill
• Ideal as a day-hike backup, an emergency grab-bag item or a first filter for DofE and Scout expeditions
• Cuts out single-use bottles on multi-day trips

Good to know

Like all straw filters it is designed for drinking on the spot rather than filling bottles or bladders. If you want to fill a 2 L reservoir for the group, pair it with our Outdoor Water Purifier pump. Blow back through the straw after each use to clear the membrane, let it dry, and store it loose in a pocket.
