Overview
Sawyer packs its hollow fiber filtration into the Micro Squeeze, a palm sized inline filter that screws onto the included pouch. Water squeezed through thousands of tiny fibers leaves bacteria, protozoa and microplastics behind, and a plunger backwashes it clean.
Its long rated life with no cartridges to swap makes it a one time buy for trips and go bags. Squeezing a soft pouch is slower work than gravity for groups. Viruses and chemicals are not in the removal claims.
Who it's for
Thru hikers, day hikers, travelers and emergency kits all suit a filter this small. Groups needing large volumes at once may prefer a gravity setup, and virus risk calls for a purifier.
Pros and cons
- Very long rated filter life
- Backwash plunger restores flow
- Fits in the palm
- Pouch, straw and coupling included
- Virus removal not claimed
- Squeezing is slow for groups
- Upper temperature limit rules out hot water
Performance notes
Flow depends on squeeze pressure and how clogged the fibers are, and backwashing with the plunger pushes trapped debris back out. The listed upper temperature limit rules out hot water.
