Rated 5 out of 5 by from My go-to in developing countries! I've been using my LifeStraw Mission for almost two years now and couldn't be happier. I'm an NGO photographer and my work often requires me to travel in developing countries where water is unsafe to drink and the plastic waste is an enormous problem. I've used my Mission in India, Zambia, and Ghana, as well as a handful of other places and have never had any issues with it. My coworkers often ask to use it when they are traveling with me, too. It's easy to use, ultra light and packable, and I've put my health in its hands many times with confidence. I love recommending it to others in my field, too.

Rated 4 out of 5 by from Great with one flaw i am annoyed by The tensioning saystem for height is cumbersome and annoying with a full bag of heavy water above gead. I measured empty, but because I had to adjust after the weighted hang, the process was slow. Also, the drip for clean is short, i can imagine that there may be some legal reason for this as because people can screw up alot of easy things, given the chance, but that is a difficulty as well" especially when filling containers of different heights. That said, i drank svuzzy water from a scank pond in low country last week and I'm not crapping blood...good sign. Just kidding, but yes, I have had no health issues with my first 2 uses.

Rated 4 out of 5 by from Gets the job done, but slowly. I got LifeStraw Mission to use on multiple day camping trips where I would have access to lakes or rivers. It's concept is easy, but this filter is not as intuitive as others. Anyone using it should first understand the two valves and method to flush. The filter does claim to have a long lifespan which is one of the best in its category. The included bag neatly packages everything for travel when not in use but it is not a filter I would take on multiple day hikes due to its overall size and weight. Hanging it in camp will require a high position due to it's tube length. The biggest downside of the filter is that it is slower than most gravity based versions. You're likely not in a hurry camping, but you will be standing a while to fill a container.

Rated 5 out of 5 by from Perfect for backup water for the family We had a recent situation where our city's water treatment plant was not able to keep up with the floods and increased turbidity in the water lead to a no-drink warning. Perfect scenario for this system, as it will filter out parasites and viruses and anything that may have slipped through the treatment plant. It is important to know what this system will and will not do. It will not filter out chemicals, but it will remove parasites, viruses, and things that will make you immediately sick. As long as you know that the upstream source of water has not been contaminated with chemicals, then this will filter and make it safe to drink. Love having this as a backup safety net for the entire family.

Rated 5 out of 5 by from Love the Features I received this item for my my son and husband to try out while out adventuring. This product can hold upto 12 Liters of water plus has the filtration straw to filter out any harmful bacteria, viruses, and protozoa from the water. It does also come with the hook to hang it from a tree branch or around your shoulder. This amazing product also comes with a bag so you can roll it up after use and put in the storage back to place in a backpack or away. This product is wonderful for summer adventures with the heat and staying hydrated.

Rated 5 out of 5 by from Easy I am impressed on how great this works. The set up is easy to do. I like that a visual manual is printed on the bag and it also comes with a paper manual in many languages. The LifeStraw Mission is ideal for camping, traveling to a different country or for an emergency situation. In any situation that you use this product in you can rest ensured knowing that you'll have clean, safe drinking water. It also comes with 4 filters and a storage bag to put away when not in use.

Does the LifeStraw Mission filter chemical matter (pesticides, herbicides) ? Thank you

Asked by: Charlotte
No I don't believe so. It should answer that question in the directions pamphlet. This filter is amazing. It worked well this summer in the Boundary Waters, filtering water for four days, for 7 guy's. It's nice that you can back wash the filter. We had a couple of high pollen days,where the water was a little dirtier. I highly recommend Life Straw Mission Filter.

We are taking the 12L to Philmont this summer. Is there a way to get just a replacement filter as a backup without the bag?

Asked by: steven69
I had a similar situation, in the end I decided it was a better deal to get the 5 liter kit on sale for $10 more than just the filter itself.
