User questions & answers

Question:	Does it filter sea salt water
Answer:	Fresh water is considered to be any water source but salt water.0.01 Microns will remove just about anything including viruses.It will remove chlorine. Try to put intake hose below the algae using the floater.I would trust this filter in almost any fresh water source, except a pool of nothing but chemicals in it.
Question:	How long is the shelf life
Answer:	According to their literature, they filter down to 0.01 microns, which is 10 nanometers (billionth's of a meter). I looked up viruses, and viruses vary in size from 20 to 400 namometers. That means the smallest virus is twice the size of the holes it would have to fit through! In other words, NO viruses should be able to get through, however, it may be possible if it was very small and constricted somehow, or if there was a minor defect in the structure of the filter, so that's probably why they aren't claiming it's totally impossible for a virus to get through.

User questions & answers

Question:	Is there a trick to getting clean water through this thing? Even Hulk Hogan couldn't squeeze hard enough as it is
Answer:	The filter should be able to process a gallon of water in less than 10 minutes. Two fixes ... 1. There could be an air bubble trapped in the filter or tube, to remove it, unscrew the end cap that is attached to the tube and filter (make sure you do not get water on the drinking water outlet), then screw the cap tight again and test the flow. 2. Use the included backwashing syringe to clear the filter, there might be much debris from turbid water slowing your flow.
Question:	Where is this product made
Answer:	Our products are made designed in Switzerland and made in South Korea.
Question:	Why does the initial filter last for 500 gallons but the replacement filter only lasts for 25 gallons? that seems like a ridiculous difference
Answer:	There are two replacements for this product. The main membrane would still last for 500 gallons of water and then the carbon capsule is 25. These are two separate filters.
Question:	Will this work for well water
Answer:	It should work for any water source. Just know, the dirtier the water, the more often it needs to be replaced. Also, it is not made to filter large amounts if water, and it's very slow.

User questions & answers

Question:	Are replacement filters available
Answer:	They ARE narrow. I want a wider size and according to the shoe size chart link, I wanted a 2E, not 4E Ultrawide, BUT Amazon Zappo's only stock the 'normal' Narrow and 4E Ultrawides. @WayneM, there is no 'half size larger' to select, apparently they don't pay attention to what people are buying and they don't bother to restock. I went ahead and ordered the D 'medium' which is actually very NARROW. The shoes came and they just fit me with the laces all the way stretched out. That said, I like them anyway - they're light and the sole is solid. The box only says size 10.5 and No width letter. And they don't show the width letter on the shoe's label either. Good shoe, not great sizing.So, Zappo's / Amazon has some work to do to avoid confusion and returns, just stock the medium wides, please. And start labeling the shoes better.
Question:	What is the flow rate
Answer:	I've been wearing them for walking for almost a year now. I started walking a few hundred yards a day last summer when I weighed 270 and by fall I was walking 6-8 miles a day! I am down to 190 and my asics venture 5s have finally begun to wear out. I normally wear orthotics but have never put them in the asics and my feet are just fine! As a side note I bought some new balance on sale a couple weeks ago and my feet immediately began to hurt! I am buying another pair of asics venture5s today!
Question:	is the storage bag BPA free
Answer:	These shoes kick A$$ and take names. These new Matt 5 running shoes are outta names now
Question:	Is there any type of warranty for the product or filter
Answer:	Yes! They have worked very well for me

User questions & answers

Question:	EBOLA! if it mutates and gets in water supply, will this remove it
Answer:	YES. The ebola virus is 0.08 microns in size. Almost no filter will remove this. BUT the LifeStraw Family filters to 0.02 microns, so yes ebola would be filtered out. That is if it mutates to survive in our water supply, which is unknown.
Question:	Does it remove contaminants such as if we had nuclear fallout
Answer:	"Food Grade Zeolite" a volcanic crystal powder, removes radiation and has been used in both Japan and Chernobyl to help absorb the radiation in the people around those nuclear disasters. Zeolite is easily mixed with food or water and taken, and 1 pound with last a family for quite some time. It was cooked into biscuits during Chernobyl and given to children, decreasing the amount or radiation in their bodies by about 60% with just one serving! The LifeStraw will get rid of the viruses and bacteria, and the Food Grade Zeolite will absorb the radiation and many other chemicals you could be exposed to ;-)
Question:	I am pretty sure the answer is not but just need to hear it for myself. Will this work on seawater
Answer:	It's pretty amazing, but it won't remove salt. Here's a link to a more in-depth review: http://www.portablewaterfilters.org/whats-new/lifestraw-family-1-0-review/
Question:	Is there a shelf life for this if it's unused
Answer:	On the next packaging run, the shelf life comment will be removed. A short shelf life was stated on original packaging as the product was designed for the high temperatures and stress of the African environment. Stored in our homes here in the USA, there's nothing to cause the product to degrade or expire. Direct and constant sunlight will cause any plastic to eventually degrade, which is why the lifespan statement was developed. If you use it for camping and periodically use and store it, it's a good idea to flush it with tap water and allow it to dry before storing.

User questions & answers

Question:	does it produce only h2o
Answer:	Only thing I can find is on the sawyer website is the lifetime warranty so if you read it the will fix/replace the filter for life as long as you dont modify the filter in anyway or open the housing or run juice or drink mixes thru it they will replace it the 100,000 gallon guarantee is to tell you you will have it for life you will lose it beforeit breaks I hope I was of help you can find all the tech data sheets on there website
Question:	Is the "ultra filter" just another name for hollow-fiber membrane filter? if not, what is the material in the "uf
Answer:	You are right about the 2 ounces being the filter only-that is what Sawyer advertises. The entire unit, inside the packaging is 4.8 ounces. I cannot take it out to weigh the items outside the packaging as I would need to destroy the container to get them out. I am guessing the plastic covering weighs less than an ounce so the entire unit probably weighs about 4 ounces.
Question:	Your literature says " removes contaminants from Fresh Water". What about algae covered ponds and swimming pools?s
Answer:	This filter is advertised as up to 100,000 gallons by Sawyer. When you begin to notice a decrease in flow, I recommend back flushing with potable water using the included syringe. I normally keep an ounce or two of 90% isopropyl alcohol to sanitize the drinking tip and any tubes I may use when setting up different systems. After use and before long term storage (especially if you filtered a lot of biologically questionable water), it is recommended to run a sanitizing solution of bleach/water (1tbsp plain, unscented bleach to 1 gallon water) through the filter then rinse very well with potable water, shake out vigorously and allow to air dry for several days before capping and placing into storage. An unopened filter should have indefinite shelf life unless it is subjected to extreme temperatures, hot or cold.
Question:	Does this filter viruses
Answer:	Sawyer's claim for the filter is that it removes 99.99999% of all harmful bacteria and 99.9999% of protozoa. Viruses are not included nor are other impurities mentioned. I have written to Sawyer to ask about tannin and brackish water and will reply again once I receive a return message. I'm not sure when that will be, but hope it will be soon.Keri-LynnFour Seasons Survival

User questions & answers

Question:	What are the dimensions of the bottle
Answer:	Yes. The pump does not remove chemicals; acids, oil, gasoline, ect. It is best used in waters that have biological agent contamination; bacteria,viruses, amoeba, particulate matter. It cannot be used in salt water.
Question:	is there any unusual taste to treated water and should it be filtered
Answer:	We used the filter pump on a 4 day trip camping and it worked well, but it does take some effort to maintain your water supply as the pumping can take a while and be a little tedious.
Question:	How many gallons of clean water will the bottle give
Answer:	The only contaminants this product will remove are those with a physical size of .2 micron or greater. This is sufficient to remove bacteria and protozoa. It DOES NOT use any sort of active chemistry in the filtration process, therefore it cannot remove or neutralize any dissolved chemicals, viruses or heavy metals present in the water. Therefore, it is exceedingly unlikely that it would be of any use in a bioterrorism attack.
Question:	Some reviews have stated that their product was old and expired. Are these new? And how long would they last in my BOB? Thank you
Answer:	I would think you would order them front the manufacturer.

User questions & answers

Question:	I have to use a sinus pulsation machine which requires either boiled or distilled water. Would these tabs work in tap water for this
Answer:	If by 'use it' you mean 'make it drinkable', then no; the LifeStraw won't remove the salt that makes sea water unsafe to drink. So, it's probably not the ideal solution for your yacht's emergency lifeboat kit. If you're boating on freshwater rivers or in swamps, however, it should remove all the particulate crud in that water, making it drinkable.There are personal desalination/emergency hydration kits available (HTI's SeaPack, for example, is available on Amazon) that can be used to make sea water drinkable. Try a web or Amazon search for 'personal desalination' and you should be able to find them. You might also want to consider an emergency solar water still to produce purified, desalinated water.
Question:	will the water purification tablets kill protozoa including giardia and cryptosporidium
Answer:	There's actually no longer a shelf life listed. It was initially 3 years, then 5 years, and now Vestergaard of Switzerland (the manufacturer) has removed the notice completely. They were designed for use in African countries where the constant hot sun degrades any plastic, and the shelf life notice was created in case some users left them outside for years in the sun. Turns out it wasn't much of an issue to worry about, so the shelf life notice has been lifted. You can use it, store it, and use it again without problem. Just be sure it's totally dry inside before storing - in fact you can store it uncapped to be sure.
Question:	What is the expiration date? When was it made/packaged
Answer:	Short answer: NO. Here are some details (apparently the Lifestraw has a .2 micron microfilter):•A microfiltration filter has a pore size of approximately 0.1 micron (pore size ranges vary by filter from 0.05 micron to 5 micron);•Microfiltration has a very high effectiveness in removing protozoa (for example, Cryptosporidium, Giardia);•Microfiltration has a moderate effectiveness in removing bacteria (for example, Campylobacter, Salmonella, Shigella, E. coli);•Microfiltration is not effective in removing viruses (for example, Enteric, Hepatitis A, Norovirus, Rotavirus);•Microfiltration is not effective in removing chemicals.
Question:	I am looking to put these in my car in a Northern region where the temperature reaches -50 degrees F will these still work
Answer:	Salt and urea, along with various other substances your body is trying to eliminate, will remain in the filtered urine so it will still taste like pee (whatever that tastes like.) In a desperate survival situation, many people have resorted to drinking their urine. That is ok up to a point. As your dehydration increases, your urine will become increasingly concentrated (dark and even viscous.) It's best to drink urine early in your survival situation since it will be less concentrated and consequently less toxic. That way you are conserving what water you do have longer. Of course, most people will completely exhaust their water supply before they resort to drinking urine. However, drinking highly concentrated urine is probably worse than not drinking it at all. Also, urine is actually sterile inside your bladder but not as it flows through your urethra. Happy drinking!
