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 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 your 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, allowing for sustained flow over a long period. With a sturdy carrying feature, it can easily be attached to a backpack with a carabiner or rope. The filter capacity 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.
