Step up your water filtration game with the LifeStraw Peak Series! Just released after three years of extensive research, the Peak Series consists of a redesigned Straw, 650 ml and 1L Collapsible Squeeze Bottle Water Filter System, 3L and 8L Gravity Water Filter System, and 8L Gravity Water Filter + Water Storage Bag. LifeStraw redesigned their Personal Water Filter Straw, the most popular outdoor water filtration device available, by making it smaller, improving the grip, enhancing the flow rate for easier sipping, incorporating a built-in gravity hose attachment, as well as including universal threading for attaching to squeeze bottles (we especially love this feature!). Who knew you could improve on an already great design?! We also tested the new 650 ml Collapsible Squeeze Bottle Water Filter System, an all-in-one water storage and filtration device, that is built out of the most durable material available. This baby can take a beating (can we say butterfingers!) without worry of breaking or leaking! Both items are fitted with a membrane microfilter that removes 99.999% of bacteria, parasites, and microplastics and will filter up to 1,000 gallons (4,000 liters) for the straw and up to 500 gallons (2,000 liters) for the bottle without needing replacement. As an added bonus, this socially responsible, Certified B corporation donates an entire school year’s worth of drinking water to a child for every LifeStraw product purchased. Also, LifeStraw has responded to the growing Ukrainian refugee crisis, by shipping over 800 purifiers and filters to Romania to be distributed to refugees and internally displaced peoples. Make a positive impact on your backcountry experience and even more importantly, on the world with the new LifeStraw Peak Series!
