The LifeStraw Peak Series Solo water filter is an ultra-lightweight, compact, and portable water filtration device that removes bacteria, parasites, microplastics, silt, sand, and turbidity from drinking water. Thanks to its 28mm 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 use. Weighing less than 50g 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 long-term flow rates. Extremely versatile: standard 28mm 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.
