The LifeStraw Peak Series Solo water filter is an ultralight, compact, and portable water filtration device that removes bacteria, parasites, microplastics, silt, sand, and turbidity from drinking water. Thanks to the 28-mm standard thread, the filter can be screwed onto most common water bottles. The one-handed twist cap allows for easy and quick filtering on the go: a 1-liter bottle can be filled in just 20 seconds. Ideal for hiking, backpacking, camping, emergencies, travel, or on the go. Weighing less than 50 grams and with a capacity of 2,000 liters of clean drinking water, it is an essential item for any backpack, bag, emergency kit, or glove compartment. The improved microfilter performance reduces clogging from sand and silt, ensuring better flow rates over time. Extremely versatile: standard 28-mm PCO thread for attachment to standard water bottles. Made from high-quality, durable, 50% recycled BPA-free plastic. Includes leak-proof caps on the top and bottom. LifeStraw is proud to be a certified B Corp and climate-neutral brand. For every purchase, a needy child receives safe drinking water for a year.
