## Description

LifeStraw’s Peak Series filter membrane density has been re-engineered for optimized flow rate - meaning better performance against sand and silt while maintaining great flow for the long haul. This highly versatile filter is designed to be interchangeable, featuring universal threading to make it as adaptable as possible to all your gear. Your purchase has impact: For every LifeStraw product purchased, a school child in need receives safe water for an entire school year.

Review: Just don’t forget it when you travel! - This is my new travel companion! I use a CPap and I am always looking for water with no salt, and most bottled water has added things for taste! No more trips to the store as usual! The sink water works perfect thru this! No hassle ! No danger of bad water near your brain!
Review: Nice option to compare against Sawyer and the other brands - Neat filter ecosystem with multiple sizes of bags and other attachments. When I bought it I didn't realize that the filter can also be screwed onto most standard 1L or 1.5L water bottles, which a huge plus if you want to use something disposable to store unfiltered water and save the 3L storage bag for filtered/clean water.

## Features

- Protects against 99.999999% of bacteria (including E.coli, Salmonella), 99.999% of parasites (including Giardia and Cryptosporidium), 99.999% of microplastics, silt, sand, and cloudiness
- Enhanced microfilter performance: Our re-engineered membrane and custom backwash accessory means better performance against sand and silt, maintaining great flow over the long haul
- Ultra-compact, our reconfigured filter is tiny but mighty and doesn’t sacrifice weight or space
- Use with the collapsible squeeze bottle, gravity water filter system or as a standalone straw
- Your purchase has impact: one purchase, one child, one year of safe water
