Rated 5 out of 5 by from Saved my Life I spent 3 Months Trekking through Peru, Colombia & Costa Rica. Through rural, isolated communities and urban areas, all of which had horrendous water quality. I often relied on my LifeStraw for my sole source of hydration. I drank water from Rivers, Lakes, Streams and Urban faucets that can often lead to contracting diseases and parasites. My friends had a running bet as to when my "newcomers luck" would run out & I would become sick. I never did. It's a durable and reliable product that I love. I have brought it on all of my adventures and wouldn't travel without it!

Rated 2 out of 5 by from Tastes awful First off, this waterbottle is durable and relatively easy to use. We have used it to filter river water, tap water, etc. BUT. Regardless of where we used it, the water tastes absolutely awful. The bottle/filter gives it a nasty old plastic taste that honestly cannot be described with words. Go with a hand pump filter for better value and better tasting water.

Rated 5 out of 5 by from Reviewers need to follow instructions I just bought a two pack of these and then looked to see more reviews. It appears those who said there was a nasty taste probably didn't follow the instructions for the bottle. You have to take the carbon filter out and rinse everything. I just did that and the water tastes good and normal, no nastiness.

Rated 5 out of 5 by from Makes Hydration A Snap I love this product... super easy and convince to use. no need to carry a lot of water. Attach to pack or just carry, fill and hydrate at any source of water along your trek.

Rated 5 out of 5 by from Lighten your pack Weight is king in so many environments, especially the caving one. The technology compact life straw is a game changing piece of equipment that has allowed me to free my pack of water weight. I would recommend it to everyone. The water always tastes great from it.

Rated 2 out of 5 by from Filter prep The pre-use preparation requires you to remove and rinse the charcoal filter. It says you should be able to remove it with your fingernail or a small coin, this was impossible I broke the tab off 2 water bottles. Disappointed

Rated 1 out of 5 by from Can't Get Past Taste I was so excited about this water bottle. I work in a building with nasty tasting tap water. I was hoping a water bottle with a filter would solve my problem but, after filtering, the water only has an equally nasty taste. I really tried to get past it as, generally speaking, this is reviewed broadly as one of the best out there but I can't get past the foul chemical taste. I will, unfortunately, be returning my bottle and continue my quest for a filtering water bottle to use at work.

Rated 2 out of 5 by from What's up? Had to buy this one to replace the one I got last year which I had only used once for a 3 day hike. The replacement worked fine but I am a little skeptical about the trustworthiness of the Life Straw. I hope the 1st one was a rare defect.

I bought the LifeStraw bottle with the carbon filter If I need to replace the filter is it the same filter for both types of bottles? Where is the carbon ? Is it in the Straw mouth piece ? If so do I need to replace it ever

Asked by: Leon Waller
"LifeStraw Go 2-Stage Replacement Filter" and "LifeStraw Carbon Replacement Filter" are two separate replacement products. The carbon filter's useful life expectancy is about 1/10th of the life (in gallons) of the water filter itself.

How do you know whether  it's time to replace the filter?

Asked by: NaughtyHiker
The flow rate will decrease and then stop pulling water through once it reaches the end of its life.

I'd like to use this for a long international trip. Does it filter metals or common chemical contaminants from tap water? And for hiking purposes, would very cold temperatures damage the filter or reduce how well it works? Thanks!

Asked by: SandyO
​The LifeStraw Go 2 uses an activated carbon capsule to reduce organic chemical matter for up to 100 liters – 26 gallons. Using it with cold water will not hinder its effectiveness.

I understand the Lifestraw will stop working when it is time to change the filter but how will we know which filter (carbon or the other -not sure the name) needs to be changed? Can 2-stage Lifestraw water bottle be used without the carbon filter?

Asked by: VioletHiker
The straw filter is recommended to be changed when the flow rate decreases, which is up to 1,000 liters. The carbon capsule is important and needs to be changed every 3 months.

We are setting out on the A.T. in June. I have researched many of these water treatment systems. Would you personally recommend this product for first time hikers? And, what sets this apart from other products?

Asked by: Countrycricket79
This filter bottle is a great option for first time hikers and backpackers. This system is a great water filtration system for a single person use. Unlike other water filter systems, this allows you to carry the water and drink from the bottle like you would a traditional water bottle. When you are out of water and reach your next water source refilling the bottle is an easy process.

Does the water suck through the straw easily, or is it an arduous or slow process?

Asked by: Ivan Ofelich
​It is a little different from drinking out of a normal water bottle or normal straw, but it is easy and most people do not find it arduous.
