How LifeStraw Mission Works
LifeStraw Mission uses a highly efficient method of purification that requires no chemicals, batteries or moving parts. Water poured into the purifier moves down the tube, while being forced through narrow hollow fibers. Clean water exits through tiny pores in the walls of the hollow fibers, but bacteria, viruses, protozoa and other contaminants are trapped inside and are flushed out by backwashing.
- Easy-to-remove, 80-micron pre-filter inside bag; also includes extra pre-filter screens
- Purifier is easy to clean in the field, thanks to integrated back-flush bulb
- All raw materials are US FDA compliant or equivalent
- Water passes through the meter-long blue PVC hose and gravity creates sufficient pressure on the membrane cartridge in order to reach a high flow rate.
- Ultra filtration takes place in the hollow fiber membrane cartridge – a pore size of 20 nanometers (0.02 microns) retains bacteria, viruses, parasites and fine dirt particles.
- The blue tap is turned to release purified water.
- Backwash the membrane by squeezing the red backwash bulb 3 times with both taps closed and then releasing the dirty water from the red tap. Water from the red tap should never be consumed.
The Science Behind LifeStraw
Backed by serious research in international labs and extensive testing in the field, LifeStraw and LifeStraw Family have been distributed to nearly every major international humanitarian disaster since 2005 and in broad public health campaigns in the millions.
The same high-tech design used in places like Haiti, Indonesia, South Africa, Kenya, Democratic Republic of the Congo, Pakistan and Bangladesh is now available in the USA and Canada.
Does the LifeStraw Mission require a power source?
The LifeStraw Mission is a gravity filter and does not require any power source. No batteries or electricity is needed.
Does the LifeStraw Mission remove viruses with iodine?
The LifeStraw Mission filters out contaminants without electricity, moving parts or chemicals. It will remove 99.999% of viruses through advanced filtering technology.
Does the LifeStraw Mission filter out salt water, heavy metals, chemicals or viruses?
The LifeStraw Mission is designed for hikers, campers, travellers and other outdoor enthusiasts. It will filter out 99.9999% of waterborne bacteria, 99.999% of waterborne viruses and 99.99% of waterborne protozoa. LifeStraw Mission does not remove chemicals or salt from salt water and should not be used with ocean water, sea water or brackish water.
How will I know when the LifeStraw Mission has reached 18,000L of water?
LifeStraw Mission has an auto-clog mechanism. If the product does not deliver water despite the backwashing and pre-filter cleaning, it means that the life of the product is over. LifeStraw Mission will filter on average about 10 liters of water an hour and can filter more than 18,000 liters over the product’s lifecycle. That is enough to provide a typical family of five up to three years worth of clean and safe water.
Can I drink pool water with LifeStraw products?
Pool water contains chlorine and other chemicals. LifeStraw products can only filter out bacteria, viruses and parasites, not chemicals.
What is the shelf life of LifeStraw products?
LifeStraw products use mechanical 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 room temperature, the LifeStraw will last indefinitely until it reaches capacity…even after use!
Can the LifeStraw Mission be frozen?
If your LifeStraw Mission 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.
How do I clean my LifeStraw Mission?
After every use, clean the pre filter inside the dry bag and rinse out the bag. 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. Note: water from the red tap is not filtered and therefore not safe to drink. Detach the quick release to separate the dry bag from the filter and let both dry before storing them.
It is taking a long time for water to come out the blue tap on the LifeStraw Mission – any tips?
When you use your LifeStraw Mission 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 dry bag 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.
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, 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.
Can I replace the pre filter in my LifeStraw Mission?
Yes – you can get LifeStraw Mission pre filter replacements.
What does the LifeStraw Mission purify?
The LifeStraw Mission removes 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.
LifeStraw is manufactured by Vestergaard Frandsen, a Swiss company specializing in disease control products for developing countries. Their core business model is centered around corporate social responsibility, and helping countries reach their United Nations’ Millenium Development Goals with products designed to prevent vector and water-borne diseases.
Awards & Accolades
LifeStraw has received significant accolades since its original design was invented in 2005. Time magazine named LifeStraw the “Best Invention of 2005.” In 2008, it won the Saatchi & Saatchi Award for “World Changing Ideas.” Esquire called LifeStraw the “Innovation of the Year.” Forbes stated LifeStraw is “one of the ten things that will change the way we live.”
