Rated 5 out of 5 by from An Emergency Preparedness Must Have As a single mother of an autistic child, it was long overdue that I put together items for emergencies. A Lifestraw is priority number one when gathering items for an emergency preparedness kit. Lifestraw was the first of it's kind in convenience for filtering water sources and guaranteeing clean water filtration. I am so thankful for genius inventors who see imperative product ideas and make them affordable for everyone!

Rated 4 out of 5 by from It is small, and compact and easy to use. I drank water through it and it seemed to function as intended. The reason that it did not get a 10 was because I tried it on chlorinated water and the water still tasted chlorinated. I travel a good bit where there are water fountains and my filter I have does a good job of filtering out chlorine. When I shop for a water filter I want it to do both. This is a good product and I would recommend it to my friends, but I would tell them it didn't filter out the chlorine taste.

Rated 5 out of 5 by from I have tried the LIFESTRAW Personal Water Filter in the Applegate River in southern Oregon, which is a relatively clean river with little sediment. Although there is a slight organic flavor to the unfiltered river water, the water obtained through the LIFESTRAW Personal Water Filter tasted like tap water. On the downside, a substantial amount of "suck" is required to operate the device, and it probably would not be useable by children or someone who couldn't generate the necessary pressure. Also, it is possible that the device would be even more difficult to use with turbid water. On the upside, the device appears to work as advertised (.2 microns of filtration is the same as a Katydin), is light and easy to carry, and is relatively inexpensive. Probably should be in a list of "10 essentials" for any trip away from treated water.

Rated 5 out of 5 by from In any natural disaster or out camping or hiking trip where purified water is not available, one could use the LIFESTRAW Personal Water Filter Water Filter to drink from any water source available, especially if a person is unsure how long they will be unable to have drinkable water as the human body can only function for 3 days with out water before it starts to shut down.

Rated 5 out of 5 by from I have multiple straws and thankfully do not use them often. They work great when needed and are very easy to pack. One thing that is often missed with the straws is the need to prime them prior to use. Once primed they work great. I will order more as needed.

Rated 4 out of 5 by from Pretty convenient personal item for emergency water. Light weight and low bulk make it easy to toss into your pack and not worry about it until you need it. I still prefer a water filter so that water can be filtered and transferred away from the source.

Rated 3 out of 5 by from as an emergency tool it works fine- easy to use and very straightforward. the suction required to get water is stronger then I would like, so would only use if other purification methods not available. Tested this weekend at Moraine Lake :)

Rated 3 out of 5 by from The LIFESTRAW Personal Water Filter is definitely a useful product, but I never really saw the practicality of carrying a straw around when you can use other filters to fill portable water containers to drink from at your leisure.

Once you have used the lifestraw for 4000 litres of water, can you replace the filter or do you have to buy a whole new straw ?

Can I use this from the latter on the beach?

Asked by: Anonymous
You can use this filter for any fresh water source (i.e. fountains, tap, rivers, lakes, etc.). LifeStraw removes bacteria and waterborne parasites but this particular product doesn't remove chemicals or salts. So is not appropriate for use with sea water.

What is the shelf live of this product?

Asked by: BDavis
LifeStraw products don't have an expiration date. They use hollow-fiber membrane to remove contaminants from the water source. No chemicals or moving parts are involved within the filtering process, meaning nothing will expire. If stored in a cool, dark and dry place and allowed to dry out between uses, the LifeStraw will last until it reaches capacity.

How much water can the lifestraw filter at once?

Asked by: max27
We estimate that the average user can pull around 1.2 L / min. with the Lifestraw, which is only a little bit less than the water you would get drinking through a regular straw.
