This is the pattern that scared me most.
People buy it for emergencies. Store it properly. Then when they need it - completely clogged.
And here's the fix from LifeStraw's own website: soak it in coconut milk for an hour.
Coconut milk. In an emergency. When you need water now...
The Survivor Straw has a simple backflush option.
Debris builds up? Flush it out in seconds and keep going. No bleach. No coconut milk. No waiting.
And it lasts for 1,800 gallons - nearly double the capacity.
That's the difference between hoping your filter works and knowing it will.
