LifeStraw Peak Series Personal Water Filter for Hiking, Camping, Travel, and Emergency Preparedness, 1 Pack, Mountain Blue

LifeStraw Peak Series personal water filter is the updated generation of the original LifeStraw with improved hollow-fiber technology that removes 99.999% of bacteria and protozoa plus microplastics — addressing the microplastic filtration capability that the original LifeStraw design didn't include. The Peak Series updates the membrane construction for improved flow rate and the housing for easier cleaning while maintaining the core straw-format portability that made the original LifeStraw the personal filter category standard.

Peak Series vs. Original LifeStraw

The original LifeStraw provides reliable bacteria and protozoa filtration at an accessible price point. The Peak Series adds microplastic filtration — an emerging concern as microplastics have been identified in virtually all natural water sources worldwide. If microplastic filtration is a priority (for high-use natural water sources where plastic debris is common), the Peak Series provides the additional filtration layer. For backcountry use in pristine mountain water sources where microplastic contamination is lower, the original LifeStraw provides adequate protection at a lower cost.

• Updated hollow-fiber membrane — removes bacteria, protozoa, and microplastics
• Improved flow rate vs. original LifeStraw — faster drinking in the field
• Straw format — drink directly from water source without pump or bags
• 1,000-liter filter life — multi-season reliability for backpacking
• Field-cleanable design — maintain the filter in the field by blowing backwards

LifeStraw Peak in an Emergency Kit

Like the original LifeStraw, the Peak Series has a 5-year shelf life in original packaging — suitable for emergency kit inclusion and long-term storage. Its compact form factor and simple operation make it appropriate for emergency scenarios where unfamiliar users need to filter water without instruction or equipment setup. Keep one in a vehicle emergency kit, go-bag, and backcountry day pack as insurance against unexpected water access loss during any outdoor activity.
