LifeStraw®Universal Water Filter Bottle Adapter Kit with 2-stage filter fits Selected Bottles from Hydroflask, Camelbak, Klean Kanteen, Nalgene and More

The LifeStraw®Universal is the first bottle adaptor kit with a 2-stage filter, that allows you to turn your favorite bottle into a powerful water filter.

How it works

Add an advanced LifeStraw® filter to your favorite reusable water bottle with this adapter kit featuring a LifeStraw® filter and 2 caps that fit most narrow and wide-mouthed water bottles. The LifeStraw® technology contains a specially designed hollow fiber ultrafiltration technology. The first stage of filtration features a replaceable hollow fiber membrane microbiological filter which filters to 0.2 microns and removes 99.999999 percent of waterborne bacteria and 99.999 percent of waterborne protozoan parasites. At the second stage, the additional activated carbon filter improves taste while reducing chlorine, and organic chemical matter such as pesticides, herbicides, and VOCs.

The LifeStraw® Universal filters up to 4,000 liters of contaminated water without using iodine, chlorine, or other chemicals. LifeStraw® products do not require batteries, have no moving parts and use no chemicals. This water filter displays a great and more innovative alternative to iodine tablets and bulky purifiers. The LifeStraw® technology has been independently tested and certified to meet EU directive 10/2011 and EU directive 1935/2004 regulatory standards.

    Does your website have a contact page? I'm having problems locating it but, I'd like to send you an email. I've got some recommendations for your blog you might be interested in hearing. Either way, great website and I look forward to seeing it grow over time.

    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.

    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!

    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.

    LOVE IT ! LOVE THIS ITEM!!! MY boyfriend received one for Christmas, and I was sooooooo jealous! Now I have one of my very own!! This is SUCH a useful item and I am really pleased with this addition to this months box! I also love all the different attachments to be able to use it with many different water bottles and such.

    This is really cool. I love that I can throw it on my kleen canteen or Nalgene bottle. It's a little bulky in the bottle, but the opportunity to refill whenever near water is not a big deal in places I usually hike. I have other lifestraw products that I haven't really used much, but I'm hoping to make this one a part of my regular hiking gear packing list this summer.

    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.
