This is the carbon capsule replacement for the LifeStraw Steel. By now you likely have read that the Steel has a dual-stage filter: hollow fiber membrane (HFM), and a small carbon capsule at the bottom. The HFM lasts for 1,000 liters and is not replaceable, but the carbon capsule lasts for 100 liters and is replaceable.
Replacing the carbon capsule in your LifeStraw Steel is quick and easy to do. Simply unscrew the bottom cap of the LifeStraw Steel and gently remove the carbon capsule. Discard the used one.
