LifeStraw Peak Series Solo Water Filter

LifeStraw Peak Series Solo Water Filter provides fast, reliable access to safer drinking water wherever you are.

Weighing just 48g, this compact personal water filter fits easily into any backpack or pocket while delivering exceptional filtration performance. The advanced 0.2-micron membrane microfilter removes 99.999999% of bacteria, 99.999% of parasites, and 99.999% of microplastics, along with silt and sediment, helping you drink confidently from streams, lakes and rivers. It meets US EPA and NSF P231 standards for bacterial and parasite removal.

Unlike traditional straw filters, the Peak Solo is incredibly versatile. Drink directly from the source, screw it onto most standard 28mm water bottles, or use it with compatible squeeze bottles and gravity systems. The impressive 3 litres per minute flow rate means less waiting and more exploring.

Constructed from durable 50% recycled BPA-free plastic, the filter includes leakproof top and bottom caps to keep it clean in your pack, along with a backwash syringe to maintain peak performance. With a filtration capacity of up to 2,000 litres, it's built to accompany countless outdoor adventures.

Lifetime: The membrane microfilter lasts up to 500 gallons (2,000 litres) and will stop allowing water to flow through once it’s reached the end of its lifetime. 

Please note: This filter will not work with salt water.
