The opinion of Aventure Nordique

The Peak Series Gravity Purifier 8L from LifeStraw is a gravity-fed water purifier. With a porosity index of 0.02 microns, it eliminates bacteria, parasites, suspended particles and viruses.

  • 99.99% of viruses (Rotavirus, Hepatitis A)

  • 99.999999% of bacteria (E. coli, Salmonella...)

  • 99.999% of parasites (Giardia, Cryptosporidium...)

  • 99.999% of suspended particles (microplastics, silt, sand, etc.)

The Peak Series Gravity Purifier 8L water purifier consists of an 8-litre tank with a strap to secure it in place. It is extended by a 1.20-metre hose with a hollow-fibre filter membrane at the end. Compact and lightweight when folded, it's easy to transport.

This filtration system is ideal for use at base camp or when camping. With a flow rate of 0.5 litres per minute, you can filter the 8-litre tank in 15 to 20 minutes. The membrane filter has a lifespan of 18,000 litres, long enough even for long journeys, without needing to be replaced. What's more, the system comes with a syringe for simple, quick and effective backwashing!
