With the LifeStraw® Peak Series Collapsible Squeeze Bottle Water Filter System, you'll always have a safe, clean bottle of water on hand. A highly versatile design lets you use it as a water bottle, a straw, to push water through it into cooking containers, or to connect it to other Peak Series systems (not included). It meets US EPA & NSF P231 drinking water standards for the removal of bacteria and parasites, and the re-engineered membrane even protects against 99.999999% of bacteria, 99.999% of parasites, and 99.999% of microplastics, silt, sand, and cloudiness. The membrane microfilter lasts up to 500 gal. A custom backwash accessory helps protect against sand and silt while maintaining optimal flow. Thick, leakproof, and extremely durable construction stands up to wear and tear in the field. BPA-free and FDA-approved. Robust carry feature lets you connect the bottle to your pack with a carabiner or rope. Includes squeeze water bottle, microfilter, backwash plunger, and user manual.
