FAQs

Follow the Liters

  • What is LifeStraw Follow the Liters?

    LifeStraw® ‘Follow the Liters’ is an ongoing program where, for each LifeStraw® filter or purifier purchased by a consumer, a child in a developing community will be provided with safe drinking water for an entire school year.

  • How does Follow the Liters work?

    When a consumer purchases any LifeStraw® product, a portion of the funds are used to distribute LifeStraw® Community water purifiers to primary schools in developing communities that don’t have ready access to safe drinking water. This includes educating users on proper use of the purifier and maintenance and follow-up.

  • How is Follow the Liters different from other programs?

    Unlike some programs which involve a charitable donation or partnership with outside organizations, LifeStraw Follow the Liters is a self-sustaining program that is implemented by Vestergaard, the same company that makes LifeStraw products. Also, the same quality of LifeStraw technology that is used for our travel and outdoor purifier products is used (in a larger product- LifeStraw Community) in the Follow the Liters school programs in developing countries. This way you know that the contribution goes directly to the school program and the same quality and reliability of the LifeStraw products that you love are the same that is being provided to students. We ensure transparency in the program by providing all the information about the is being provided to the student in the program. Program progress can be tracked on www.followtheliters.com. Every year, LifeStraw users join us for the Follow the Liters distribution of new LifeStraw Community purifiers to new schools! Follow us on social media to find out how to join us!

  • How many distribution campaigns have taken place?

    Large scale distribution began in October 2014 in Kenya. There, over 14 days, 1,646 high volume LifeStraw Community purifiers were distributed to 301 schools across Kenya’s Western Province. Now, 157,000 students there have access to safe drinking water. The next LifeStraw® Follow the Liters distribution will take place in November, 2015, providing over 2,500 additional LifeStraw® Community purifiers to over 300 more primary schools in western Kenya. The total impact of the program is projected to grow to over 360,000 students reached by end of November, 2015.

  • How are consumers involved?

    The LifeStraw® ‘Follow the Liters’ program is designed to allow consumers to understand exactly what their contribution is and the impact it has. We engage consumers by providing specific and measurable data on the program’s progress and achievements. As consumers take more responsibility for bridging the equity gap with communities that have less, it reduces the burden that donors and governments currently face.

  • What percentage of my purchase goes towards LifeStraw Follow the Liters?

    For each LifeStraw product sold, a portion of the sales price goes toward the distribution of our large-volume LifeStraw Community purifiers to schools in the developing world. A number of factors make it difficult to extract the percentage of each purchase. First, the price (and therefore the profit) of each LifeStraw product varies. Second, costs to deliver the LifeStraw Community purifiers differ by school location, transportation costs, and other supply chain factors. Lastly, we go beyond simply delivering water filters where they are needed – we ensure our contribution also supports training on usage, long-term maintenance of the purifiers, health education for the students, and follow-up visits by Vestergaard staff for at least 3 years. This shared effort between Vestergaard, retailers, and our distributors ensures that the LifeStraw Community purifiers remain active and that the impact on school children is long-lasting.

  • How long will each LifeStraw Community work and how many school children can one unit supply?

    The LifeStraw Community purifier has a lifespan of 70,000-100,000 liters depending on water turbidity and local conditions. Each unit serves approximately 75 to 100 school children per day. LifeStraw Follow the Liters supports filter maintenance and replacement, ensuring that usage of each unit can be maximized.

  • How are the recipient schools selected?

    Every year, a set of schools is selected based on need.  We prioritize schools with the poorest water sources and a lack of treatment options. We also consult closely with local health officials and consider recommendations from the local education offices. Before making final decisions, we visit each school to have a discussion with the school administration, confirm the student population, and assess school capacity.

  • How are results and impact monitored?

    Vestergaard uses mobile phone technology to survey all schools in the program on a quarterly basis to ensure that their LifeStraw Community water purifiers are working properly, that schools continue to practice complementary health and hygiene behaviors, and to assess the benefits of the program. Information on the number of follow-up visits conducted by staff is publicly available at www.kenya.followtheliters.com. This is updated in real time as local staff members upload data collected during each school visit.

General FAQ

  • How does the LifeStraw work?

    LifeStraw filters (LifeStraw, LifeStraw Go) use hollow fiber membrane micro filtration with a 0.2 micron pore size. LifeStraw purifiers (LifeStraw Family and LifeStraw Mission) use hollow fiber membrane ultra filtration with a 0.02 micron pore size. This means that dirty water goes into the LifeStraw, microorganisms are physically removed and safe drinking water comes out. Imagine really small tubes with even smaller pores that trap contaminants, but allow water to flow through. All LifeStraw products do not use chemicals, do not require pumping and do not require any energy input (like batteries).    

  • What do LifeStraw filters and purifiers remove?

    LifeStraw filters (LifeStraw, LifeStraw Go) remove 99.9999% of bacteria and 99.9% of protozoa. LifeStraw purifiers (LifeStraw Family and LifeStraw Mission) remove 99.9999% of bacteria, 99.999% of virus and 99.99% of protozoa.  

  • What is the difference between LifeStraw filters and LifeStraw purifiers?

    LifeStraw filters (LifeStraw, LifeStraw Go) remove 99.9999% of bacteria and 99.9% of protozoa present in water using hollow fiber membrane micro filtration. They have a 0.2 micron pore size that physically eliminates bacteria and protozoa from water. This meets US EPA drinking water standards. LifeStraw filters provide safe water for 1,000 liters (264 gallons). LifeStraw purifiers (LifeStraw Family and LifeStraw Mission) remove 99.9999% of bacteria, 99.999% of virus and 99.99% of protozoa that is present in the water using hollow fiber membrane ultra filtration. They have a 0.02 micron pore size that physically eliminates the bacteria, virus and protozoa from the water. These purifiers also meet the US EPA drinking water standards. LifeStraw purifiers provide safe water for 18,000 liters (4,755 gallons).

  • What do LifeStraw filters and purifiers NOT remove?

    LifeStraw filters (LifeStraw, LifeStraw Go) and purifiers (LifeStraw Family and LifeStraw Mission) do not remove contaminants that are dissolved in water including chemicals (like arsenic) or salt from salt water. They should not be used in areas where there is known chemical contamination and should not be used in ocean water.  

  • Does my purchase of a LifeStraw product have an impact?

    Yes! For every LifeStraw filter or purifier you purchase, a child in a developing country is provided safe drinking water for an entire school year. Vestergaard, the company that makes LifeStraw products, implements these programs ourselves, delivering high-volume LifeStraw water purifiers (LifeStraw Community) to the schools to ensure that the school children receive them, that they are well maintained and that we can track and monitor progress of their use. We make all of the details of this program and where the impact is happening available online. You purchase a product, we deliver safe drinking water to a school in a developing country and you can track the progress. “Follow the Liters” with us! Check out the Follow the Liters page to learn more.

  • Are LifeStraw filters and purifiers sensitive to temperature?

    We do not recommend LifeStraw products to be stored in areas that are consistently above 110 degrees Fahrenheit / 43 degrees Celsius. Freezing the LifeStraw can damage the filter. If your LifeStraw product has been used and the filter has water in it, freezing temperatures can make the water expand and damage the filter. If your LifeStraw has frozen after use, you should not use it.

  • Where do LifeStraw products come from?

    LifeStraw products are designed in Switzerland by Vestergaard and our technology partner is in South Korea.

  • How do I get in contact with the LifeStraw team?

    Email info@lifestraw.com

  • Where can I donate a LifeStraw?

    You can donate LifeStraw products through Rotary International: www.rotarywaterprojects.org

  • What is the shelf life of LifeStraw products?

    LifeStraw products use hollow-fiber membrane filters 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 place and allowed to dry out between uses, the LifeStraw will last until it reaches capacity.

LifeStraw

  • How does the LifeStraw work?

    The LifeStraw uses hollow fibre micro filtration to mechanically remove contaminants down to 0.2 microns. Imagine really small tubes with even smaller pores that trap contaminants, but allow water to flow through. You can stick the LifeStraw directly into a river, lake, stream or other open, fresh water source and drink water directly from the straw!

  • What does the LifeStraw filter?

    The LifeStraw removes 99.9999% of waterborne bacteria, including E. coli, and 99.9% of waterborne protozoa, including Giardia & Cryptosporidium. LifeStraw also reduces turbidity, filtering down to 0.2 microns.

  • How long will my LifeStraw last?

    The LifeStraw can filter up to 1,000 liters (264 gallons). This would mean, if you used the LifeStraw every day, for all of your drinking water, it will last for approximately one year. If you just use it for travel and outdoor activities, it will last much longer than 1 year.

  • How will I know when the LifeStraw has reached the end of its life?

    The flow rate of your LifeStraw will decrease, and then stop pulling water through once it reaches the end of its life. You can increase the lifespan by cleaning the LifeStraw after each use. The great thing is, you can never drink contaminated water from a LifeStraw; when the water stops flowing through it, you know it is time for a new one!

  • I’m having trouble sucking water through my LifeStraw – any tips?

    When you use your LifeStraw for the first time, or when the filter is completely dry (after storing, for example), it takes a little longer to prime the filter. We recommend holding your LifeStraw vertically in water, with the water about half way up the filter, for 30 seconds before using. This will help get the membranes moist and make it easier to pull water through. Make sure you keep the mouthpiece dry so it doesn’t become contaminated.

  • How do I clean my LifeStraw?

    After every use, backflush your LifeStraw by blowing a breath of air back into the mouthpiece to purge all remaining water trapped within the filter. If you have access to clean water, suck some into the filter and backflush it again. Give it a few shakes and leave both ends uncapped to air dry at room temperature.

  • Does the LifeStraw filter out heavy metals, chemicals or viruses?

    The LifeStraw is designed for the backcountry and will filter out 99.9999% of waterborne bacteria and 99.9% of waterborne protozoa. Chemicals, salt water, heavy metals and viruses will not be removed. If you were looking for a high capacity filter to remove viruses, the LifeStraw Mission and LifeStraw Family 1.0 remove 99.999% of viruses.

  • Can I drink pool water with the LifeStraw?

    Not a good idea. Pool water is usually treated with chlorine and other chemicals. LifeStraw will only remove bacteria and waterborne parasites, not chemicals.

  • Will bacteria live within the filter if not properly back flushed?

    The LifeStraw traps bacteria & protozoa, so you do not need to worry about any coming through the filter. To prevent any bacterial growth inside the mouthpiece, we recommend leaving the caps open so it dries out for a day before storing.

  • Can the LifeStraw be used on sea water?

    LifeStraw cannot remove salt and cannot be used on sea water, ocean water or brackish water.

  • Is the LifeStraw dishwasher safe?

    No. The heat of the dishwasher could warp the casing and possibly damage the filter. To clean, simply rinse with water, and leave uncapped to dry.

  • Can the LifeStraw be frozen?

    If your LifeStraw has been used, and is then exposed to freezing temperatures, water inside can freeze and crack the filter. You may not see these cracks, so we recommend never letting it freeze once it’s been used. When camping at high elevations or freezing temperatures, be extra careful not to let it freeze.

  • Is the LifeStraw BPA Free?

    Yes it is BPA free and completely safe to drink through.

  • Comment fonctionne le LifeStraw?

    Le LifeStraw utilise un système de micro filtration par fibres creuses pour enlever mécaniquement les contaminants jusqu’à 0,2 micron. Imaginez de minuscules tubes avec des pores encore plus petits qui retiennent les contaminants mais laissent passer l’eau. Vous pouvez mettre le LifeStraw directement dans une rivière, un lac, un ruisseau ou toute autre source d’eau douce accessible et boire directement à la paille!

  • It is taking a long time for water to come out the blue tap on the LifeStraw Family – any tips?

    When you use your LifeStraw Family for the first time, the purifier is completely dry (after storing, for example), and it takes a little longer to prime the filter. We recommend that you fill the blue top bucket completely and open the red tap for 3 seconds to let water pass through the filter. Close the red tap and let the filter prime for approximately 1 minute. Then, turn the blue tap on. As the filter gets wet, the flow rate increases. Note: water from the red tap is not filtered and therefore is not safe to drink. If you are still having trouble getting it started, make sure the red tap and blue tap are closed and squeeze the red bulb until it is fully compressed. Then open the red tap for 3 seconds. This should push any trapped air out of the filter. Close the red tap, and let the red bulb fill up with water and then turn the blue safe water tap back on. Note: water from the red tap is not filtered and therefore is not safe to drink. If the flow rate is slow, try backwashing the filter several times before restarting it. To do this, make sure both the red tap and blue tap are closed, and squeeze the red bulb 3 times. Each time, the bulb should be compressed fully and then allowed to refill completely. After squeezing the red bulb 3 times, open the red tap for 3-5 seconds to release the dirty water. Repeat this process as necessary to restore flow. Note: water from the red tap is not filtered and therefore is not safe to drink.

  • How do I clean my LifeStraw Family?

    After every use, clean the pre filter inside the blue bucket and rinse out the bucket. With both taps closed, squeeze the red bulb 3 times. Each time, the bulb should be compressed fully and then allowed to refill completely. Then, open the red tap and let all the water drain from the filter.
