  • Can the LifeStraw Steel be frozen?

    If your LifeStraw Steel 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.

    LifeStraw Steel cannot remove salt and cannot be used on sea water, ocean water or brackish water.

LifeStraw Steel does not remove salt from salt water and should not be used with ocean water, sea water or brackish water.

  • How do I clean my LifeStraw Steel?

    After every use, backflush your LifeStraw Steel by blowing a breath of air back into the mouthpiece to purge all remaining water trapped within the filter. You can also suck water and then blow it back through the filter. This will help remove air that might be trapped. Leave the caps off until the product fully dries before storage.

  • I’m having trouble sucking water through my LifeStraw Steel – any tips?

    When you use your LifeStraw Steel for the first time, both stages of filtration are completely dry (after storing, for example), and it takes a little longer to prime the filter. We recommend that you hold the filter vertically in the water, with the water half way up the filter, for 30 seconds before using. This will help get the membranes moist and make it easier to pull water through.

  • Can I replace my carbon capsules in my LifeStraw Steel?

    Yes- you can get LifeStraw Steel carbon capsule replacements

  • How will I know when the LifeStraw Steel has reached the end of its life?

    The flow rate of your LifeStraw Steel will decrease, and then stop pulling water through once it reaches the end of its life. You can increase the lifespan by cleaning the LifeStraw Steel after each use. It is important to change your carbon capsule every 3 months after first use to ensure that the first stage of filtration is working well.

  • How long will my LifeStraw Steel last?

    The LifeStraw Steel can filter up to 1,000 liters (264 gallons) and the replaceable carbon capsule should be changed every 3 months.
