The recommended temperature suggestions for our products are:  

  • 33 degrees Fahrenheit/1 degree Celsius  
  • 140 degrees Fahrenheit/60 degree Celsius  

Note that if the LifeStraw has water in it and is stored in freezing conditions, the creation of ice within the membrane can damage the filter by expanding the pores with the expansion of the ice.  Therefore, we recommend keeping LifeStraw products, more specifically the membrane filters close to your body when hiking or traveling in freezing temperatures to ensure any water or vapor inside the filter does not freeze.
