How do I use the filter straw?
Remove the cap, dip the end of the straw into the water and suck through the mouthpiece.
You can drink directly from the source (river, lake, fountain) or from a container: glass, water bottle, bottle.
After use, put the cap back on once the straw has drained.
What kind of water can I filter?
Choose clear fresh water: rivers, streams, lakes, natural springs and fountains, rainwater, melted snow, well water of known quality or tap water.
Be careful with stagnant water or water that has an odd smell or colour, algae or foam. Also avoid rainwater collected from roofs and wells of unknown quality.
Never use seawater or brackish water, wastewater or sewage, or water that may be contaminated by chemicals, oil, fuel, pesticides or industrial or agricultural discharge.
If in doubt about a water source, choose another one.
Can I drink seawater?
No. The filter straw does not remove salt from seawater.
How long does the filter last?
The filter straw can treat around 1,500 to 2,000 litres of water.
The actual lifespan depends on water quality, how often you use it and how well it is maintained.
It fits in your pocket and saves the day

I took it on a day out: tested it on a very murky stagnant fountain, then in a river. The result: clear water, no aftertaste and no discomfort after drinking. Two handy ways to use it: drink …

Fit the straw onto the body of the tube, blow a little air into the tube to push the air out of the straw, and suck... job done. Super practical, quick to set up, light, compact... Faultless!

A great water filter for all your hikes. The filter effectively removes all impurities from the water, the taste isn't affected and the product is good quality. What more can I say, except that I was really surprised by the quality of this product!

All questions
Getting started
Why do I need to suck harder than with an ordinary straw?
The UF membrane filters down to 0.01 micron. This very fine filtration naturally creates resistance, so it's normal to have to suck harder than with an ordinary straw.
Which water can I filter?
Can I filter anything other than water?
No. Use the filter straw with water only. Never filter sugary or fizzy drinks.
Maintenance
What should I do after each use?
Blow several times into the mouthpiece, in the opposite direction to sucking, to push out any remaining water.
Then let the straw dry completely in the open air, in a dry, well-ventilated place.
Don't leave the straw damp for several days in a plastic bag or an airtight container.
How do I clean the filter straw?
Rinse the outside of the straw with clean water. Never use soap on the filter straw and never put it in the dishwasher.
Any water still held inside the straw stays on the unfiltered side and does not contaminate the filtration system.
My filter straw was stored damp for a long time. Can I use it again?
Mould may have developed. We recommend replacing the filter straw.
What should I do if the flow becomes weak or the filter seems blocked?
Suck up a little water to wet the filter straw, then blow firmly several times into the mouthpiece, in the opposite direction to sucking. Repeat several times if necessary.
If the flow is still unusually weak after several attempts, contact our customer service team via the Contact page.
Filter, guarantee and delivery
How do I know when the straw needs replacing?
