LifeStraw Peak Personal Straw | Which replacements do I buy for my Peak personal water filter?Updated 2 months ago

Trick question!

There are no replacements for the Peak Series water filter straw, since it acts as its own filter. Once it has reached the end of its lifetime (4000 liters of water!), the membrane microfilter will stop allowing water to pull through. At this point, it will be time to replace your full Peak Series straw filter.
