Our take on the Lifestraw Membrane Microfilter Replacement

This is the replacement membrane microfilter for LifeStraw personal water filters, the hollow-fiber cartridge that does the actual cleaning. It removes bacteria, parasites and microplastics down to 0.2 microns and keeps working for up to 1,000 gallons (4,000 liters) of water, far longer than most squeeze-filter cartridges. It suits hikers, campers and emergency-kit owners who already own a LifeStraw and want to keep it running instead of buying a new filter. The trade-off is that it only fits LifeStraw housings, so it is no use with Sawyer, Katadyn or Grayl systems.

What reviewers say

Owners of LifeStraw filters generally treat the replacement cartridge as a straightforward way to extend the life of a filter they already trust. Most say it restores flow and water taste, while a few note the flow slows over time and that cleaning is needed to keep it going.

What people mention
  • Flow rateMixedOwners say a fresh cartridge restores flow, but it slows again as the filter collects sediment.
  • Water tastePraisedUsers report the filtered water tastes clean and clear.
  • LifespanPraisedThe long rated capacity is seen as good value against smaller cartridges.
  • FitMixedIt slots into LifeStraw housings easily, but owners of other brands find it does not fit.
  • MaintenanceCriticisedBackflushing and cleaning are needed to keep the flow up, and there is no wear indicator.

Questions and answers

How long does the replacement filter last?
LifeStraw rates the membrane microfilter for up to 1,000 gallons (4,000 liters). That is roughly five years of typical hiking use, or one person drinking about a gallon a day for nearly three years.
What does it remove from water?
It filters out bacteria, parasites and microplastics down to 0.2 microns. It does not remove viruses, and it will not take out dissolved chemicals such as heavy metals or salt.
Which LifeStraw filters does it fit?
It is made for LifeStraw personal and go-series filters that use the membrane microfilter. It does not fit Sawyer, Katadyn, Grayl or other brands.
How do I know when to replace it?
There is no built-in indicator. Replace it when flow stays weak after backflushing, or once you have filtered close to the rated 1,000 gallons.
Can I use it on tap water as well as streams?
Yes. It works on any fresh water source, including tap water, though cloudy or silty water will clog it faster and need more frequent backflushing.
