It's time to stop carrying a bag with plastic parts and multiple water bottles. The compact Peak Squeeze Filter from LifeStraw is an all-in-one solution for water storage and filtration. Made from premium materials and robust enough to withstand great adventures without worrying about cracks, breaks, or holes. It is ultra-lightweight, weighing only 102 g/110 g, and is also collapsible. Extremely versatile, it can be used as a straw filter, gravity filter, or, thanks to the collapsible squeeze bottle, as a press system for water supply. The density of the filter membrane has been optimized for flow rate, and the overcap and Smart-Seal mouthpiece prevent leaks. Enhanced microfilter performance: The redesigned membrane and special backwash accessory ensure better performance against sand and silt, maintaining flow over an extended period. Thanks to its sturdy carrying feature, it can easily be attached to a backpack with a carabiner or rope. The filter performance lasts up to 2000 liters. The LifeStraw Squeeze Bottle is available in sizes of 1 liter and 650 ml, as well as in two colors: Dark Mountain Gray and Mountain Blue. Your purchase makes an impact: LifeStraw's Doing Good program provides a needy child with clean water for a year. Additionally, LifeStraw is proud to be a certified B Corp and climate-neutral brand committed to meeting the highest standards for verified social and environmental performance, transparency, and accountability.
