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.
