Great for travel and does the job.
I used this little filter during plane flights and hotel stays to avoid and uncomfortable tummy issues while on vacation. I hurt my knee and when filled with cold water it doubled as a "ice bag". It isn't very big and it would need frequent filling if you're drinking a lot of liquids. I liked that it's collapsible when empty and didn't take up much room in my carry on. Nice little product.

Water safety i can trust
I've used Lifestraw products for years and this one didn't disappoint. The 1L capacity is convenient for backpacking and canyoneering water storage. I was pleased to find out that the filter can be removed and fits my 600ml trail running hydrapak bottles too. So I dont have to buy an additional filter. I tried a knockoff and ended up breaking the cap which just ended leaking critical drops of water. The Lifestraw one wouldn't have that problem. The flow rate is superior to the knock and filtration must be great because I've used it in water sources with high likelihood of waterborne contaminants (presence of animal and rodent tracks, algae, completely stagnant water) without illness. The taste isn't always the best in some of the more questionable water sources but i dont expect it to turn squirrel broth into Voss water. Just keep the enterics out.

Awesome!
I’ve never used anything like this before and I loved it! Purchased the 1L size for my June/July trip to Peru. Let me tell you that the water in Cusco had a strong smell and it ran milky white out of the tap. This filtration system removed all of that! I brushed my teeth, rinsed out refillable water bottles and cups, and washed/rinsed my invisible aligners with this. During long tours I carried it with water and there was no spillage. I loved that I could just squeeze it directly into what I needed (cup, aligners, bottles, my hands). Without squeezing there’s a nice steady flow of water that runs out of the filter which is nice. Initially the water will have like a charcoal taste, but it goes away after a couple of uses. Make sure you backwash the filter and rinse out the bag. It comes with the backwash syringe and it’s easy to use. Hint for removing the filter without it dropping: The top part of the bag is a stiff plastic, hold onto that when removing/twisting the cap for removal. DO NOT hold onto filter inside the bag while you twist off the cap for removal.

Great for travel!
We bring this on the road so we can filter water in hotels along our route. It’s great because unlike the drinking bottle, you can squeeze water into a coffee pot or hot water heater. My daughter borrowed it to take to a holiday in the DR because she wanted to be sure her water didn’t have any incompatible bugs or contaminants. It works fairly quickly, but we’ve learned to use the water right away rather than store it in the bag. Water sitting in the bag overnight in the fridge developed a funny taste. Not sure if it was from the filter or the bag itself. It does come with its own charcoal filter that is replaceable. The primary filter is good for a really long time. We have Lifewater drinking bottles and a pitcher that haven’t left the water with a funny taste. I think it may be because this bag is designed for hiking and emergencies so the filtration is extremely effective.

Works wonderfully & travels well
I highly recommend this! I purchased it for an overseas mission trip to Africa. It folds up & packs well for travel. I used it in very rural villages where bagged water was all that was available. Before my trip I was cautioned against drinking bagged water, so I bought this in preparation. It comes with instructions for usage & long term storage. It also comes with a syringe for backwashing the filter in case it gets clogged & sluggish. I currently have mine with a salt solution for long term storage. It helps the filter not dry out & it’s explained in the included instructions how to do this. It’s foldable, but the material is very sturdy. When I had it full & was drinking, I squeezed it fairly hard & threw it in my backpack many times. It remained sound. I also love that each purchase provides clean drinking water to very deserving people. I witnessed true poverty during this trip to a 3rd world country, & everyone deserves clean drinking water.

Run farther with this bottle
Great for hiking and running. The filter works very well and allows for longer runs where clean water is not available. Easy to fill and clean. Does not leak. There’s a bit of a plastic taste from the bottle but it’s not too bad

Antes de escribir una reseña he esperado para probar el producto, pues puedo decir que no pensaba que podía funcionar tan bien! He usado esta botella en dos viajes, a Jordania y Brasil, rellenando siempre con agua de grifo y no he tenido problemas. El filtro funciona de maravilla y tiene un sabor raro solo un poco al principio porqué nuevo. La botella aguanta mucho y es pratica porqué se puede doblar cuando está vacía. Recomendado 100%

Skickades tillbaks då den var trasig vid leverans. Det märktes att paketet var öppnat innan jag fick det. och korken måste ha varit åtdragen för hårt för gängorna hade spräckt plasten vid flaskhalsen. Att den dessutom var tidigare använd och inte ny i förpackning gjorde mig besviken.

Wat een heerlijk, fijne LifeStraw is dit! Voor het eerste gebruik wel goed de handleiding lezen of de instructievideo van LifeStraw bekijken. Ook om het filter werkend te houden is dit van belang. Om de chemische smaak weg te krijgen heb ik een alternatieve tip: de LifeStraw (ZONDER FILTER!) met wat water en een beetje tandpasta vullen. Dichtmaken en goed schudden dat het lekker gaat schuimen. Vervolgens leeg knijpen en een paar keer naspoelen. Het filter zelf meermaals goed doorspoelen, en daarna heb je misschien nog een beetje mint-smaak van je tandpasta, maar voor de rest heerlijk fris water! Wat heerlijk om veilig water uit de bergstroompjes te kunnen drinken.

Used a few times and so far so good, filled up at few water sources with no ill effects nice and portable. I like the fact you can attach directly to a normal soft drinks bottle. Cleaning isn't too bad, long term storage is a bit challenging requiring to be stored wet. It's great quality though and worth while investment if your a hike or a camper.
