Questions?Frequently AskedQuestions
Everything you need to know about outdoor water filtration.
How long does a single filter last?The straw is rated to filter up to 5,000 litres of water depending on the turbidity of the source. For typical hiking, trekking, and emergency usage, one single unit can comfortably last several years.
Can I screw it onto regular plastic bottles?Yes! The straw features dual-thread threading engineered to screw directly onto standard 28mm neck bottles (such as everyday soft drink or water bottles), squeeze pouches, and hydration bladder hoses.
How do I clean and maintain the straw?Extremely simple: after drinking or filtering, blow clean air back through the straw to flush out lodged silt and trapped particles. Store it dry with both protective end-caps secured until next time.
What types of water can I filter?The 0.01-micron hollow-fibre membrane filters out physical sediment, micro-particles, and suspended impurities from fresh outdoor sources. Please note that like all membrane straw filters, it is not designed to desalinate seawater.
Does it alter the taste of the water?Not at all. Unlike chlorine or iodine tablets, this straw uses 100% mechanical filtration through hollow fibres. There are no chemicals, no weird tastes, and no waiting period—just crisp, pure mountain water.
