Rated 5 out of 5 by from Truly universal I used the lifestraw universal with my hydroflask wide mouth. It worked wonderfully. It fit securely with no leaking. The water that came from the bottle was awesome! I used it at a hotel and drank from the tap, the water tasted much better coming from the bottle than the tap into a glass. The only downside is that I can see some situations where I would want to use ice while traveling, since the hydroflask can keep ice all day, but there is not enough room to add ice with the straw in place. I tried, many ways but it simply can't work with this design. Overall I think I will use this alot while travelling.

Rated 5 out of 5 by from BikePacking here I come! At first I was completely disappointed with this. I already have several ways to filter water and this didn't seem like it would fit any of my bottles. Totally wrong! When I discovered that it fit my bike bottles I was thrilled because its so small and easy to fit in my pack for when I'm not using it, but being able to stop and fill up my water when I'm on the trail is clutch, I'm constantly trying to spare all the water I can, now I can drink freely on my long rides! I also love that it fits my new bottle that came in the Obsidian-that's some nice Cairn coordination!

Rated 5 out of 5 by from It's About Time! I was so happy to receive this. I have purchased many of the LifeStraws (straw) for friends and family, but not for myself. I seem to collect water purifiers and already had SteriPENs, MSR MiniWorks, the original Katadyn and the Katadyn Hiker Pro and 2 of the bottles w/filters. I like the versatility of the LifeStraw Universal. It's about time! Like all filter type bottles, you have to pull hard on it to get it going, but that's okay . It beats pumping water. It is very portable and I can use it on my go-to Nalgenes . Great invention!

Rated 5 out of 5 by from Changed my mind At first I was skeptical of LifeStraw usefulness. However, after using it with wifey on our training hikes for upcoming backpacking season, I'll always carry LifeStraw on hikes when there will be water access. The LifeStraw saves us a few pounds of water weight, super easy & easy to use and we are always well hydrated. Have been pondering if we could get away with individual LifeStraws as our water filter on backpacking trips. Have recommended this to a long distance cyclist friend after he asked my opinion on LifeStraw.

Rated 1 out of 5 by from Beware - Unfiltered Water possible Update: The LifeStraw is great addition to my backpack. However there is one fatal flaw. We discovered this weekend that one needs to be careful to insure the LifeStraw is still connected to the water bottle lid. During hiking it easily disconnects from the lid, thus you will be drinking unfiltered water. If you hear rattling in the water bottle, the LifeStraw has disconnected. Always check before drinking.

Rated 5 out of 5 by from Lifestraw Universal A great additional way to use the Lifestraw. The original Lifestraw is awesome, but doesn't mate to a container while the Lifestraw Go does, but involves purchasing a container when we all probably have plenty of those already. This approach also allows use of the Lifestraw with different bottle types. Very flexible in use and easy to keep all parts together in the convenient storage bag.

Rated 5 out of 5 by from Water Filter Swap Outs These attachments to act as a lifestraw are very nice. It actually fits on some other bottles I have as well, so it doesn't have to be exactly the same brand. It comes with multiple tops too, just in case you have different sized bottles. Very convenient and nice to use on long hikes or overnight trips, instead of bringing bladders or other water filtration systems that can be bulky.

Rated 3 out of 5 by from I like the lifestraw brand and I like that it came with multiple bottle attachements, but the filter connection to the bottle is not very secure. I only tested it out with tap water from home, but when as I carried the bottle with me hiking this weekend, the filter would detach from the nozzle. If I were worried about the water source I think that would be a pretty big problem.

Can this also remove viruses and protozoan cysts?

Asked by: Realistic
All of our products would remove protozoa. Only our purifiers, Mission, Family, and Community, remove viruses. This would not.

Can you please tell me if the lifestraw universal will fit on a Camelbak Groove water bottle? It is not listed on your compatible/incompatible list. Thank you.

Asked by: Mai2
This is not on our list because it was not tested with our kit. The Universal kit may be compatible with select models, with a 7.3” minimum bottle height. The measurements of the cap/lid are: Wide mouth cap outer diameter: 2.75 in | 7 cm, threading diameter 2.5 in |6.3 cm Narrow mouth cap outer diameter: 2.28 in |5.8 cm, threading diameter 1.7 in | 4.3 cm We hope this helps!

On the lifestraw go steel page, it says the carbon filter lasts 26 gallons. On the lifestraw universal page, it says it lasts 100 gallons. which is it? thanks.

Asked by: SeaPort
Hi there! We just checked this information, and on both the Steel & Universal pages, the information is the same. The carbon capsule lasts for 100 Liters of water.

Hi, if I'm not mistaken, this produit allows pouring water in a glass instead of using it as a straw, can you confirm this please? Also, does the Lifestraw Go allow this too? Thank you for your answer!

Asked by: DelphineFR
You cannot pour water from the Universal or Go bottle. If you need a bottle you can pour, the Flex is the only one that does this.

Hi, I would like to use this product or the Lifestraw Go on a daily basis for about a year, is it really important to change the carbon filter? And how many of them will I need? Knowing that I will use it everytime I need to drink. Thanks for your answer!

Asked by: DelphineFR
The carbon filter must be changed after 100 liters of water. When you notice the smell and the taste of water have changed, this means it's time replace it.

Does this fit a Thermoflask bottle? Couldnt find it in the list of bottles this fits/doesn't fit. Also, does LifeStraw do the "give back" no matter where you buy the product from or only if you buy it directly from the lifestraw site?

Asked by: VickyTee
I have a 40 oz thermoflask that I bought from Costco that fit the cap.

Will this work with a 64oz hydro flask?

Asked by: Cheyenne406
Mine came with two sizes for caps: Standard and Wide Mouth. If I’m not mistaken, it should fit a 64oz hydroflask, because it needs a wide mouth cap.
