Rated 5 out of 5 by from Lifestraw was a lifesaver in Zion NP Last week, we went hiking up a slot canyon in the Zion National Park wilderness area on a trail that leads to The Subway. Like an idiot, I took off without two water bottles. It was a 90 degree day on a 10-mile out and back trail. Two years ago, I bought a LifeStraw at REI, but never used it. It was my lifeline on this hike. Every 15 minutes, I got a drink out of ice cold North Creek. The LifeStraw worked perfectly. I had no stomach issues despite drinking heavily from the creek. Please buy yourself a LifeStraw just for these kind of wilderness situations where dehydration can happen quickly and weaken you.

Rated 5 out of 5 by from Amazing Product! I had seen videos of this so-called "LifeStraw" and, after gleaning some information from the web, I was intrigued enough to buy the product, but did not have high expectations; after all, is it not just a straw? Boy was I wrong. Not only was the LifeStraw convenient to use - the user-friendly manual gets a 10/10 from me - but it managed expectations. Albeit, I am not someone who is particularly adventurous or takes pleasure in backpacking or hiking, rather, someone who is genuinely interested in sustainability. From filtering nasty, bacteria filled water to juices (for fun), the LifeStraw did not disappoint!

Rated 5 out of 5 by from Saved Our Lives My boyfriend and I went on a backpacking trip along the Ice Age Trail in Wisconsin that ended in nothing but disaster. Night one our (very expensive) water pump broke and we were stuck in the middle of no where with no potable water and a 3 day hike out. Thank goodness he had brought along his LifeStraw because I can honestly say it saved us on that trip. It was our only means of getting clean water other then boiling it and we relied on it for the remaining 3 days of out trip in the back country. We used it to drink right out of rivers and lakes because there was barely any water along the trail. We figured we would get sick because the Straw is so small, light and compact that there was no way it could filter the all but bog water we had to drink but it did! We were 100% fine and the water even tasted good. I will never go on a backpacking trip without it again and highly recommend this product to anyone who is an ultralight backpacker like myself.

Rated 5 out of 5 by from Personal Water Filter We recently purchased 2 of the Personal Water Filters for emergency purposes. We trust Lifestraw will take excellent care of us if we ever need to use these filters. We have been using the Lifestraw Water Bottles for the past year and love the clean and crisp water taste from the filters. We wouldn't use anything else for our daily water!

Rated 5 out of 5 by from An Emergency Preparedness Must Have As a single mother of an autistic child, it was long overdue that I put together items for emergencies. A Lifestraw is priority number one when gathering items for an emergency preparedness kit. Lifestraw was the first of it's kind in convenience for filtering water sources and guaranteeing clean water filtration. I am so thankful for genius inventors who see imperative product ideas and make them affordable for everyone!

Rated 5 out of 5 by from Survival kit I bought this for my son for Christmas who is an air cadet and wanted it to include in his survival kit. I’m not sure what he is surviving but when he saw this he thought it was necessary! When I looked into it further it looked like a great product that gives back to those in need and I appreciated that about the company.

Rated 5 out of 5 by from Awesome Product I live in the Pacific Northwest and spend lots of time outdoors, often in remote areas and I always bring my Life Straw. I’ve also given them as gifts on multiple occasions. I love the peace of mind.

Your invention sounds wonderful :) I am a bit confused though, why does it say that only 1 year of water is provided for the school child after every purchase? I thought the straws last for 5 years or 4000 litres (which is 2.19 litres a day over 5 years)

I have 2 lifestraws that I keep on hand for emergency, I did notice that on  the package, there is a 5 year self life. Manufacture date on the straws is 2013. Should I discard? 

Asked by: Henry007
Our products do not have a shelf life. They can be used until the 4000 liters as long as they are stored in a cool, dry place and not exposed to any elevated temperatures.

Can I use the straw in South America against most common waterborne pathogens? 

Asked by: Jaz99
The products you purchase would depend on the water quality of the region. If you haven't yet, we suggest contacting a local travel doctor for the best information. Our customer support team can also send a contaminant removal sheet that lists our products and what each one removes. For this, please email us at for assistance.

Have the company given these straws to third world countries, because 30 usd is about a mouth for a third world country. And what are your % of money to fund life straws to the Third World Countries?

Im researching your company/business for a project of mine and i would like to know that if the life-straw is manufactured with minimal carbon emission as possible. Thanks in advance!

Asked by: Matthew
And how exactly do you offset emissions? Offset means there are still emissions. That sounds like a sales pitch to me.
