How to store the GO Series Waterbottle or Tumbler

When your LifeStraw GO Series bottle or tumbler isn’t in use, we recommend storing the membrane filter in a saltwater solution. This helps prevent mold and algae and keeps the filter moist for easy use later.

⚠️ Please do not store saltwater inside stainless steel bottles—it can cause rust.

Here’s how to store your filter properly:

1. Remove Carbon Filter
2. Let it dry for 30 minutes, then place it in a sealed bag or reusable container.
3. Disinfect Membrane Filter
   • Mix ¼ tsp household bleach with 2 cups (0.5L) clean water.
   • Pour the solution into your bottle with the membrane filter installed. Close the lid and let it sit for 5 minutes.
   • Rinse twice with clean water, shaking for 30 seconds each time.

   • Blow air through the filter to remove any bleach residue.

     Prepare Saltwater Storage

   • In a non-metal container or zip-lock bag, mix 1 tsp salt with 0.5L water. Shake to dissolve.
   • Submerge the membrane filter in the solution and seal tightly.

   • Do not store this solution inside a stainless steel bottle.

     Store

   • Keep the membrane filter + saltwater in a cool, dry place.
   • Place the dry carbon filter in a sealed bag inside your bottle and close the cap.

When You’re Ready to Use It Again:

• Reinsert the carbon filter.
• Discard the salt solution and reinstall the membrane filter.
• Fill the bottle with water and spit out the first few sips if they taste salty.
• If stored for more than 3 months, we recommend replacing the carbon filter.
