The LifeStraw Steel Water Filter builds on the ingenuity of the original LifeStraw with a durable, sleek steel exterior and 2-stage water filtration so you can sip straight from a stream or lake.

  • Features

    • 0.2-micron filter physically removes 99.9999% of all bacteria, such as salmonella, cholera and E.coli; removes 99.9% of all protozoa, such as giardia and cryptosporidium
    • Hollow-fiber filter membrane offers a high flow rate; sip on the straw and it filters the water while it's on the way to your mouth
    • Get down close to the stream or lake and use the LifeStraw to drink straight from the source, or fill your water bottle and insert the filter to start sipping
    • Effectively filters up to 264 gal. (1,000 liters)
    • LifeStraw Steel has an activated carbon capsule that reduces chemicals such as chlorine while reducing organic compounds (including pesticides), odors and bad tastes
    • Replaceable carbon capsule has a lifetime of 100 liters (26 gal.)
    • No after taste because no iodine or chlorine are used
    • Weighs only 4.4 oz., making it a very light addition to your backpacking gear or emergency kit

    • Easy to clean; can be stored and used periodically—just keep uncapped so it can dry thoroughly
