Product Description

The LifeStraw Mission is a gravity-powered water purifier employing an award-winning technology that requires no chemicals, batteries or moving parts. The LifeStraw Mission removes 99.9999% of bacteria, 99.99% of protozoa, and 99.999% of viruses. The larger capacity of the Mission water purifier is ideal for providing clean water to multiple people, and is designed for camping, hunting, and other group or family activites, as well as disaster and emergency survival prep kits. The reservoir can be filled from nearby lakes, ponds, rivers, or streams and suspended from a tree or other sturdy support. Gravity moves water down the hose to the filter's advanced ultrafiltration membrane. Clean water exits through 0.02 micron pores in the walls of the hollow fibers, but bacteria, viruses, protozoa and other contaminants are trapped inside and are flushed out by backwashing. Compact, BPA-free roll bag reservoir features a wide mouth for easy filling with a convenient shoulder carrying strap for transport back to base camp or other group location. Includes drawstring stuff-sack for easy storage and portability. Includes four extra pre-filter screens for easy on-site maintenance. Produces flow-rate of 9-12 liters (2.4-3.2 gallons) per hour and will purify 18,000 liters over its lifetime. Available in 5 or 12 liter capacity. Weight: 13 oz (5L), 15 oz (12L). For each LifeStraw purchased, one child in a developing community receives safe drinking water for an entire school year

Missing parts - TWICE!
I ordered the Lifestraw Mission 12 Liter in DEC 2016 for my emergency preparedness kit. While getting ready for Hurricane IRMA in SEP 2017, I pulled the kit out to review the items and discovered that the product was missing the necessary Roll Bag, shoulder strap, extra pre-filter mesh filters and the stuff sack. I called Amazon and to their great credit, they provided a full refund of the cost of the incomplete product.I thereupon ordered a second replacement Lifestraw Mission. To my complete amazement, this second product was also missing the same items as the product received 10 months earlier. I am returning this item to Amazon.I emailed Lifestraw a week ago - so far ...crickets..........The first picture is the product as received. The second picture is the product as illustrated on another vendor's web page (NOTE the Roll Bag)

I bought this to take backpacking. We tried it out at a lake the week before our trip and learned how to use it - so I definitely recommend doing so yourself. We took it backpacking for a 3 day rough trip and used it to fill 2- smart water bottles each. It is very lightweight and well worth the price. It was so hot out that we used it twice a day and used water from a river and from small creek puddles to filter. When we compared side-by-side with actual bottled water, it was difficult to distinguish between the two. Of course, this would depend on the quality of water source too. It does take a bit to fill bottles, but we averaged about 5 min per bottle so it would take about 20 minutes to fill 4 tall bottles and was not an issue for us. I absolutely LOVE this product and highly recommend it. I think it is worth the price for good clean water and it is easy to use. It was literally a life saver for us on this trip.

Just got back from a 4-day canoe camping trip on the Colorado where this little bugger provided all of the drinking and cooking water for 6 people.

Worked flawlessly. The flow is a little slow (does 5L bag in about an hour). Not something you'd want to sit and wait for. But you put up a bottle, open the valve, and a little while later, it's full, and you go to the next. I had no trouble keeping canteens and bottles full. But you do have to stay on top of it, because the flow is limiting. Plan your camp operations ahead (hint, get water filter set up *first*), and it's a wonderful little tool.

The water coming out was perfectly clear, and tasted better than bottled water.

After 4 days, the sediment filter in the bag was still flowing fine, and the water was a little turbid, so I was impressed. Definitely will purchase another when needed.

I don't know why but I was so nervous about using this. I knew I was going to get some waterborne parasite and end up with explosive diarrhea for the rest of my life. It's been a week since we backpacked and no problems yet!
This was super simple to use, even my 11 and 9 year old kids took it down to the stream to fill it up. It was really light and fit easily in my backpack. The water does come out really slowly, it took about 20 minutes to fill up a one litre bottle but I knew that from reading other reviews, so it's not a big deal.
Pretty happy with this purchase.

I called Amazon when my original order was missing the pouch that holds the water (got only the straw) and within a day or two received the complete order! The product itself is solid and looks like it will work just fine... IF that proves not to be the case I will post that...after extensive research into Walter filter systems and both of my children using Lifestraw I am confident I’ve made the right choice.

5.0 out of 5 stars Almost perfect
Reviewed in the United States on June 12, 2017

Took this filter on a 3 day backpacking trip with 13 people. Love it. Only complaint is that it is kind of tricky to pack and not damage. The bulb to clean the filter is at a right angle to all of the shut offs... begging to get broke when crammed in a pack. I ended up strapping it to the side of my pack and was careful about where I leaned my bag. Best thing about it is that you can set it up right next to your site and do other things while it is filtering. Takes about 4 minutes to fill a liter bottle. I'll never pump water again.

We seriously LOVE this product. It did everything we were hoping on our 10 day Bowron Lakes trip and we drank from everything - cold mountain streams, small shallow lakes, deep cold lakes, silty rivers & even marshy areas. We were healthy and happy with the taste everyday. I'd read the review about how fast it was but even my husband was amazed. When we arrived at camp we set it up and it had both of our collapsible water tanks filled in no time so we were ready for the evening and the next day.
