How did we get our start?
It all began with a simple idea: a mesh filter designed as a straw to fight guinea worm disease. In 1994, LifeStraw partnered with The Carter Center to design a simple mesh filter to remove Guinea worm larvae from drinking water. Since then we have designed water filtration for outdoors and home.
What makes our products unique?
Every LifeStraw product removes bacteria, parasites, and microplastics.
Why do we love what we do?
We have humanitarian roots and believe that impact matters. To us, it's not just water filters, its ensuring equitable access to safe water for all

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

There was a problem filtering reviews right now. Please try again later.
I tested this with my tap water. I was pleasantly surprised that the tap water actually tasted different (cleaner) when passed through this filter. We have hard water, but I've never tasted a difference using regular Brita filters, or even the Lifestraw straw.
Since some of the bad reviews said it had a plasticky taste, I let the water sit in the bag overnight before drinking to see if that was true. There's no plasticky taste after 12 hours. I tried it again after 18 hours, and I could taste the plastic that they were talking about. I will try again after cleaning the system.
Other bad reviews said the water wasn't trickling out fast enough. At first, I wasn't getting water out of it, but then I *gasp* read the directions and flushed the red backwash valve, and what do you know, it worked beautifully. If you are expecting it to flow like your tap at home, I guess you might think it was slow, but I'd be worried that it was ineffective if it came out any faster. So far, this is my favorite of all my emergency water supplies.
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!
