As part of the brand’s latest Amazon sale, you’ll find the LifeStraw Peak Series Personal Water Filter for $15.89 with free shipping for Prime members or in orders over $25. Regularly $20 and sometimes as much as $25, this is up to 36% off the going rate and the lowest price we can find. Today’s deal marks the best price of the year, slightly undercutting our previous mention, and comes in at the second-best all-time on the latest model LifeStraw personal water filters. Designed for everything from emergency situations to expeditions out in the wild, these compact filters are made to transform otherwise harmful liquid into drinking water – they “protect against 99.999999% of bacteria (including E.coli, Salmonella), 99.999% of parasites (including Giardia and Cryptosporidium), and 99.999% of microplastics, silt, sand, and cloudiness.” Inside there’s a small microfilter designed to reduce clogging from silt and sand “for up to 1,000 gallons” as well as what the brand calls an “ultra leak-proof” construction to handle rugged outdoor adventures inside your hiking pack.
