Overview
A personal filter straw from LifeStraw meant as backup or emergency hydration, filtering at 2.5 liters per minute through a membrane rated for 99.999999 percent bacteria removal and up to 1,000 gallons of use.
The Peak Series updates LifeStraw's membrane to resist clogging from sand and silt, which matters most on exactly the sources, murky or fine-sediment water, where straw filters usually slow down fastest. It can also thread onto bottles or standard gravity hoses through a removable cap, so it works as a standalone straw or as part of a larger setup.
- 2.5 liter per minute flow rate
- Up to 1,000 gallon (4,000 L) lifespan
- Removes 99.999999% of bacteria
- Attaches to bottles and gravity hoses
Who it's for
Suited to backpackers and emergency-kit builders who want a durable, ultralight backup filter that can also attach to a bottle or gravity hose. Less suited to those who would rather avoid hand-to-mouth suction, since a straw filter takes sucking rather than a squeeze or press.
Pros and cons
- Fast 2.5 liter per minute flow rate
- Membrane resists clogging from sand and silt
- Attaches to bottles or gravity hoses via removable cap
- Durable, leak-proof build for rough handling
- Straw format requires suction rather than squeezing or pressing
Performance notes
A re-engineered membrane is designed to shed sand and silt rather than trap and clog on it, keeping the rated 2.5 liter per minute flow more consistent over the filter's life; the same membrane is rated for up to 1,000 gallons (4,000 L), which LifeStraw frames as roughly five years of daily personal use.
