LifeStraw Personal Water Filter


This unique invention allows you to drink directly from puddles and streams. Youc an also fill the water in your bottle and use the straw to drink from it. 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.
To clean the straw after you are done drinking, blow a breath of air back down into the LifeStraw to purge the remaining water out. Shake it well to remove excess water 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.

Cleaning Instructions
 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, minerals, or viruses. If drinking from water which may have viruses in it (e.g. contaminated by human sewage), you will need to pre-treat LifeStraw with water treatment tablets.

LifeStraw for Travel & Backpacking:
Because the LifeStraw is so small and lightweight, it’s great for travel overseas in countries with unreliable drinking water. If you’ve ever been sick while travelling, you know the importance of drinking filtered water! Make sure to drink all water through the LifeStraw.

LifeStraw for Hiking & Camping:
Access to clean water is critical while hiking. LifeStraw accomplishes the same thing as other filters, but does it at just a tenth of the weight. If you’re ultra-light hiking, this is a must. At only 2 oz, it’s the lightest way of filtering water while on the go. If you consume the recommended 3-4 liters of water per day while hiking, LifeStraw will last you for between 250-330 days of hiking. If you’re in a rush, there’s no need to stop and filter water by the lake. Just scoop your water bottle full, and sip from it as you walk. Or, dip the end of the straw right into the lake and drink until you’re hydrated.

LifeStraw removes/filters:
LifeStraw filters down to an incredible, 0.2 microns in size! This removes virtually all the bacteria (99.9999%) and protozoa (99.9%) from contaminated water, and reduces turbidity (muddiness) by filtering out suspended particles.

Bacteria removed include:

  • Escherichia coli,
  • Campylobacter,
  • Vibrio cholerae,
  • Pseudomonas aeruginosa,
  • Shigella
  • Salmonella

Protozoa removed include:

  • Giardia lamblia ("Beaver Fever")
