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

  • Best of Four Filters I’ve Used
Just returned from a remote backpacking trip. I am on Amazon to reorder my backup water purification supplies in the event of a future equipment failure while remote camping. Seeing any negative reviews makes me wonder what could someone have to say that’s negative? I see almost all one star reviews are due to the bag not coming with. I remember when I bought mine in 2017 the bag was zip tied to the package so perhaps it fell off during handling. Get another one. I’ve used four filters now and this one has been my first gravity filter. I used pumps by other brands since the 1990s and say you can’t go wrong with this bag. I have my responsible 13-year old be in charge of the water for our trips and he does a great job. We run two bags through this system each day, so that’s 24 liters. The water tastes great and hasn’t let us down. I want to address the negative reviews. For starters, if you’re mad because this system didn’t work when you were out in some remote location I’d be mad too. But for golly sake- if you’re going to rely on something to provide water test it first at home. And the bag can be adjusted to let it do its thing without watching the paint dry. If you think it runs too slow you’re not experienced enough to know the difference. Try hand pump filters and you’ll see they are no fun and appreciate these gravity filters. Everyone that’s ever used this with me says the water tastes great. If it tastes plasticy then you probably have cheap plastic bottles or reservoirs that weren’t cleaned before use or are junky and will not lead to good water. And if you’re thinking of trying some random online off brand to save some money- I’d guess again. I would never jeopardize health in a remote location to save a buck. I recommend this but also recommend that you learn how if works, try it before you go, and have a backup plan in case you fall while climbing a steep ascent or stumble in a rock garden and break the filter. It only makes common sense. Happy camper-ing! ... show more

  • Great Tasting Water. Great for large groups. Consumer Grade Product, Handle With Care.
Used this on a 3 day canoe camping trip. It did exactly what it was supposed to do: Provide water for our family of nine. It could easily provide water for many more people. The best way to manage it is to bring a large full jug of water, like 2.5 gallons, and this filter. First make sure the filter is working properly, then use all the water in the jug and refill it with this filter. If you have more people bring more full, or empty, jugs and fill them as soon as they go empty. It took about 1 hour to make 2.5 gallons of water. The water tastes great. My kids actually pointed this out. They said it tasted better than the spring water that came in the jug we bought. The instructions are clearly printed on the bag, but this did not stop one adult member of our group from drinking from the red/raw water valve. Educate all members of your group on how to use the filter. Read all instructions thoroughly and follow them exactly. I recommend this product but I would not bet my life on it, not because I don't trust that it filters the water as it says, but because it is not as durable as I would like it to be, as a piece of critical equipment. Call it consumer grade. If your going on a serious trip, bring two. I do not recommend filling the bag up to the fill line. I did that and I think I came close to breaking the carry strap and possibly the top of the bag. Water is heavy. Also the plastic hose gets permanently creased when folded. In general the tubing and bulb don't feel like the greatest quality plastic. Surgical grade plastic/rubber would be better, and for the price of this product, expected. I expect to have to cut off failed sections of the tubing at some point. ... show more

  • As expected and advertised.
It's plastic. It did have a light plastic flavor to it. I'm sure this will go away after a few uses, just like any other plastic item you drink from. I have not used this in a survival situation or camping situation yet. I only tested this device to see if the flow and production was as advertised. I am satisfied that it is. It seems to be fairly sturdy/durable. I'm sure if you abuse it, pack it wrong or fall on it while it is in a backpack you can damage or break it. I think it will suffice based on price and reviews I have read. I would buy another if I needed a second one. ... show more

  • Wonderful to have safe water in the wilderness!
This water purifier traveled on a horse pack trip into the Bob Marshall Wilderness of Montana to the Chinese Wall. Four people were on this trip. We were so grateful to be able to purify a sufficient quantity of water for our group for drinking and cooking. That said, I can understand why people said that they were surprised at the trickle of purified water that came out. I was, too. We handled this by placing a cooking pan under the outlet and simply going about other activities as the purified water collected. By doing this, we had plenty of water-patience won out. It take about 2 minutes, 10 seconds to collect a measured cup of water. That should be 10 cups in about 20 minutes or about an hour and 45 minutes for the three gallons. I loved that we could have plenty of good, drinkable water. Thank you, LifeStraw! The water purifier is a little awkward to pack. It comes with a carrying bag, but I was worried about breaking it. I did pack it in a Rubbermaid container to protect it. This is the reason that I give it 4 stars. ... show more
