LifeStraw

Personal Water Filter

Clean Drinking

LifeStraw is a personal water filter that’s simple to use, small enough to fit in your pocket, and capable of filtering 1,000 liters of water—that’s enough water for one person for a whole year.

Since 2005, Vestergaard the international company behind the product has been distributing LifeStraw to people in developing countries who don’t have access to safe drinking water. Now, LifeStraw is available for consumers as well.
Whether you’re traveling to a country where the water may not agree with you or filtering water from streams while hiking and camping, LifeStraw could be a real lifesaver. It also comes in handy for everyday on-the-go use.

LifeStraw utilizes advanced hollow fiber technology, a highly efficient method of filtration that requires no chlorine and no iodine. It has been shown to trap 99.9999% of waterborne bacteria, including E. coli and 99.9% of waterborne protozoan parasites such as Giardia.

And the best part is that for each LifeStraw sold, a year's worth of clean drinking water is provided to those in need.

    Can you take the empty water bottle with the filter on an airplane?

    @Gayleen Yes, you can take the empty water bottle and filter on a plane. It should be no problem.

    I love this, but can you filter the water without sucking through the straw to get clean water for an infant or disabled person? Or do you have another product that does?

    @Gayla With the LifeStraw Go, once the filter is primed it is easy for a child to suck water through it.

    If you wanted to provide water for an infant, you can do so through our gravity system: the LifeStraw Family.

    We are planning on releasing a more portable gravity system in the next 6-8 months as well.

    Is there anything this will NOT filter that one would want to keep in mind?

    @Nancy The LifeStraw Personal and LifeStraw Go will remove all bacteria, protozoa and turbidity, which includes Cryptosporidium, Giardia, E-Coli and other parasites.

    These contaminants are the main culprits for gastrointestinal disease and ailment such as diarrhea.

    The LifeStraw Personal & Go will not remove viruses, heavy metals, or chemicals. If you are in a region where viruses are prevalent in the water, you can always add purification tablets to the water beforehand (aquatabs, iodine or chlorine for example).

    The LifeStraw Family gravity system will remove viruses as well as bacteria & protozoa.

    Aran, This is a fatastic product. My daughter researhed the LifeSraw , bought two, and used them in a demo for her senior project on new inovative products. The staff at Vestergard were very helpful and a pleasure to talk to. I have drank local stream water through LifeStraw and was amazed how good it tasted. Loved the product Love your web site. Keep up the great work

    How long will this keep if a person buys one to keep on hand in case of disaster, etc.? In other words, will the insides disintegrate or become ineffective if unused and stored indefinitely?

  • Aran

    @Guest The hollow fiber membrane filter will last indefinitely when stored at room temperature (EG, not exposed to freezing with water in the membrane, or extreme heat that would melt plastic).

    There is nothing that should degrade with the LifeStraw.

    How can you tell when it's reached 1000 liters, or does it last 1 year from the time you first use it? Also, does washing it do any harm to the filter?

  • Aran

    @Guest The LifeStraw flow rate will reduce as it reaches the end of its life, and it will eventually stop letting water go through the filter. Once you can't pull any water through, you can dispose of it (recycle it).

    It will filter *At minimum* 1,000 litres (264 gallons). In reality, if you clean the filter by pulling in clean water and flushing the membranes by blowing it out, you can significantly extend that lifespan.

    With less turbid water it has been tested up to 1,600 litres.

    does this work for salt water as well?

  • Aran

    @Thomas The LifeStraw will remove bacteria and protozoa and turbidity from salty water, but will not remove salt from water. You would need a desalinator to accomplish this. They are unfortunately very expensive and require a high pressure pump.

    Is there something in the hollow fiber tube membrane/filter (like carbon and/or zeolite)? Or is it just holes in a membrane?

    Does it balance the pH of the water?

  • Aran
    Aran – Special Guest
    3/5/2014 4:19 PM

    @Joan The membranes have 0.2 micron holes in them, which trap bacteria and protozoa, and let water flow through. There is no carbon or zeolite, and no PH balancing.

    @Joan It will not reduce chlorine, chloramine, lead or other chemicals or heavy metals. This is not designed for city-water contaminants. For city water issues that are more chemical or heavy metal in nature, we recommend a 10 stage or carbon filter.

    @marcia the LifeStraw is: 9 inches long, 1 inch in diameter, and weighs only 2 oz.
