LifeStraw Go Series Water Filter Bottle (1 L)
A 1-litre BPA-free bottle with a built-in two-stage filter: a membrane microfilter for bacteria, parasites and microplastics, plus a carbon filter for taste and chlorine. Made for hiking days, glacier trails and any destination where you would rather not buy plastic bottles.
- Filters bacteria, parasites and microplastics from streams and taps — genuinely useful on multi-day hikes
- Carbon filter improves taste and reduces chlorine, so hotel tap water becomes drinkable water
- 1 L capacity in a light, BPA-free bottle that replaces dozens of single-use bottles per trip

Who it suits — and who should skip it
This is for travel where you cannot assume the tap is safe, and for hiking or paddling where the alternative is carrying every litre you will drink. Filter-in-the-bottle means you refill from the source instead of buying plastic.
Skip it if you mainly drink from safe taps — you are then carrying a filter you do not need and drinking through more resistance than a plain bottle. Note too that multiple buyers report leaking, especially after altitude changes or when overtightened, so it is not the bottle to throw loose into a laptop bag.
Avoiding the two common complaints
- Loosen the cap briefly when you land or descend a mountain. Pressure changes are behind most of the leak reports.
- Do not overtighten the lid; the seal works by contact, not by force.
- Backflush the filter as the instructions describe. Flow slowing down is usually a clogged filter, not a dead one.
What the filter does and does not remove
A hollow-fibre membrane filter of this type targets bacteria and protozoa — the organisms behind most travel stomach illness from surface water. It is not a purifier: viruses and dissolved chemicals are a different problem needing a different technology. That distinction matters when you choose where to fill up. For a stream in the Alps it is the right tool; for water you suspect is chemically contaminated it is not.
