The Peak Solo water filter provides protection against bacteria (including E. coli and salmonella), parasites (including giardia and cryptosporidium), and microplastics, while remaining ultralight and long-lasting with a weight of only 48.2 g (1.7 oz.) and a membrane microfilter that lasts up to 2,000 litres. It is highly versatile, as it screws onto standard water bottles, and delivers a fast flow rate of 3 L/min, allowing you to fill a 1 L bottle in just 20 seconds. Built from durable and sustainable materials, it is made with 50% post-consumer recycled BPA-free plastic, ensuring both strength and reduced environmental impact. The product includes a leakproof top and bottom cap, a custom threaded backwash syringe, and a user manual. LifeStraw is a certified B Corp and Climate Neutral brand, and for every purchase, a child in need receives safe drinking water for one year.
