LifeStraw Peak Series: All You Need for Water Filtration on the Go
LifeStraw is renowned for its compact, versatile, and effective water filters, and the Peak Series is no exception. We tested two key products from the lineup: the LifeStraw Peak Series Gravity Purifier (with virus removal) and the LifeStraw Peak Series Collapsible Squeeze 1L Bottle with Filter. Depending on your adventure, these systems can be used individually or paired together.The 8L Gravity Purifier removes 99.99% of viruses, bacteria, and parasites—making it an exceptional central filtration station for car camping, base camps, or larger groups. Meanwhile, the 1L Collapsible Squeeze Bottle offers a lightweight, convenient solution for on-the-move hydration. While the Squeeze Bottle does not filter out viruses, pairing it with the Gravity Purifier gives you full coverage across all backcountry conditions. When filtration isn't required, you can remove the filter from the Squeeze Bottle and use it strictly as a packable water reservoir.
Beyond making reliable gear, LifeStraw is a Certified Climate Neutral brand. For every purchase made, a child in need receives safe drinking water for an entire year.
LifeStraw Peak Series Gravity Purifier (With Virus Removal)
The Peak Series Gravity Purifier delivers a high flow rate of 30 L/hr, powered by a heavy-duty 8-litre capacity bag, an oversized 1.2 m hose, and gravity—no pumping required. Its Ultrafilter Membrane removes viruses (such as Rotavirus and Hepatitis A), bacteria (E. coli, Salmonella), and parasites (Giardia, Cryptosporidium), while filtering out microplastics, sand, dirt, and turbidity.
Because most standard backcountry filters cannot remove viruses, this purifier is ideal for international travel, base camps, and emergency preparedness. The filter features an 18,000-litre lifetime capacity, providing safe drinking water for a family of five for approximately five years under normal use.
Note: A standard 8L Peak Series Gravity Filter (without virus removal) is also available for $137 CAD/USD. Because it lacks the virus-purifying ultrafilter, its filtration element is smaller, reducing total weight by 214 g (7.4 oz).
