LifeStraw offers easy access to clean and safe drinking water anywhere!

A Time Magazine “Invention of the Year” winner, LifeStraw is the most advanced, compact, ultralight personal water filter available. LifeStraw contains no chemicals or iodinated resin, no batteries and no moving parts to break or wear out. It features a high flow rate and weighs only 2oz. LifeStraw is perfect for the ultralight backpacker, traveler, boy scout, hunter, and especially for emergency preparedness.

LifeStraw filters to 0.2 microns through the use of hollow-fiber membranes, which are small tubes with even smaller pores. These pores allow water to pass, but prevent contaminants larger than 0.2 microns from flowing through. As you get closer to 264 gallons (1,000 liters), the pores will eventually become clogged with debris and the flow will stop.

LifeStraw is the water filter chosen by leading NGOs for humanitarian relief worldwide since launch in 2005. LifeStraws have been sent to Africa, Pakistan, Haiti, and South America for disaster aid, and a portion of domestic sales support this donation program. LifeStraw has only been available in North America since 2011, when excess inventory has allowed it.

How To Use the LifeStraw Water Filter

Filtering your drinking water could not be simpler. With LifeStraw you can drink directly from puddles or streams, or you may find it easier to scoop water with your wide-mouthed water bottle and drink from it using the LifeStraw. When new, the filter membrane is very dry and must be primed before use. Uncap the top and bottom caps and insert the base of the straw into the contaminated water, being careful to keep the mouthpiece dry. Let it sit for 30 seconds to allow water to creep up the membrane, then take 5 quick sucks to get the water flowing. It takes roughly 3-5 seconds of sucking to start the flow of water through the filter when the membrane is dry.

When finished drinking, blow a breath of air back down into the LifeStraw to purge the remaining water out, shake, and recap. If you drink from murky water and the water flow stops, blow back into it to purge the water and mud from the filter. When you return home from a hiking trip, drink some tap water with the LifeStraw, purge the filter by blowing back into it, and leave it to dry with the caps off.

The LifeStraw will not desalinate salt water, remove dissolved chemicals or minerals, nor remove viruses. If drinking from water which may have viruses in it (e.g. contaminated by human sewage), pre-treat with water treatment tablets. See the included instruction manual for more information.

Frequently Asked Questions

  • Will this work on low level radiation contaminated water from the tap ?

    No but the low level radiation from tap water is not that high, if you are wanting to remove all radiation from your water , Amazon sells a Seychelle water straw for radiation removal, also NuWater has a TRAP total radioisotope aqua purifier sock, you just drop into 50 gallon of water and it removes all radiation.

  • Does the shelf life of 5 years begin after first use? Does it have a manufactured date on it?

    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.

  • Does it filter out chemical toxins?

    Avoid water with a strange hue or film on it, and avoid water that is not clear Try to find moving water as opposed to still water Avoid water where there is active growth in it such as algae or scum Avoid water near roadways or pavement as it likely has oil and pollutants in it Stay upstream of industrial facilities, mines and construction Avoid water from farmland, as it might have large amounts of fertilizer and pesticides in it.
